There's an interesting development called Dream Park which will be a theme park with Real-time, Real-space Live Action Roleplaying as a central vision.
A related area is computer based role playing games, the first of
which was ADVENT where you got to explore Colossal Cave. A
more-or-less direct
port has been done, so newcomers can now play this, the very
first, computer RPG with their web browser.
Hiking and camping
A large collection of Backcountry
information, including the
PATC pages,
covering some areas where I hike, and then there's the
AMC which covers more local
hiking.
GORP -- Great Outdoor Recreation
Pages has useful information for seeing the great outdoors
all across America.
Railroading, model- and -fan
I'm both a model railroader and railfan. I've been a member of TMRC
since 1973, and am presently working on a set of
experimental
web pages for them.
The best WWW resource I've found
for railroad related info is
The
Virtual Railroad another found by Alan Kotok is from the
FAQ
for rec.railroad. I also have pointers on my
Tourism page for
Amtrak,
the MBTA,
and others.
Through the web, I accidentally came across a hobby shop on the net
with my name!
It's Patton Hobby
in Georgia (I have a cousin who lives in Georgia, but it's not him :-).
Entertainment
The entertainment info has moved to a
separate page. If you got here
directly from a pointer on one of my pages, please
let me know so I can fix it. If it was a pointer on someone else's
page, you should let them know. If you were just
paging through the file, that's OK, follow the link if you want the info.
Since my researches so far have tracked only one set of ancestors out of the country, to Sweden, I'm interested in Roland Johansson's page on Scandinavian Genealogy and the Genealogy in Sweden page (unfortunately, mostly in Swedish). There's also a project to put all Swedish church records online, although they only have a few samples so far, none of interest to me.
Another extensive branch of my family is old New England families, and since I also live in the Boston area, the NEGHS is a useful resource (although the pages on-line don't have any research info). Someone else has started a page about New England History which includes some genealogy related info.
Some government resources for genealogy include U. S. Bureau of the Census and the National Archives (which includes a section specifically on genealogy). One particularly interesting resource is the Census's tabulation of name frequency in the census data.
I'm working with a group that's trying to get actual genealogical data on the web. The project is called GenWeb, and while it's still in rough outline Anders Andersson is keeping track of current status. And a collection of genealogy databases on the net. A related resource is the "Genealogical Server" GenServ, a service for making GEDCOM data available Geneanet has a surname lookup service (although I haven't tried it, yet.)
Although I presently use a home brew system for managing my data, I expect to switch to LifeLines when I get the proverbial Round Tuit.
And there's always what Ambrose Bierce had to say about genealogy in his The Devil's Dictionary.
The Space Telescope Science Institute has lots of pictures of their observations (as well as a few of the Hubble, itself).
SpaceBound is an online magazine dedicated to astronomy and space exploration.
I'm a member of The Planetary Society.
The online catalogs for Hello Direct and Cincinnati Microwave have products I'm interested in. AmeriCom Long Distance Service provides a worldwide Area/City/Country Code Lookup Service, and thedirectory has a service that lists Area and exchange codes throughout the U.S. There is a lot of useful Area Code info at LincMad including a map and historical listings of splits, and the original (1947) area code assignments.
There's also a collection of pointers to Telephone Directories On The Web including the NYNEX Yellow Pages (the one local to me).
Reverse directories are available from AnyWho from AT&T Labs and from 555-1212.com (that's the common telephone "info" number in the U.S.) The AnyWho listings can draw maps using MapsOnUs and can generate other interesting related listings.
