Aha - the glint of tupperware under the leaf cover!
It has been some time since I have done geocaching and early this morning seemed appropriate. If you are looking for a good excuse to get a GPS, give this a try.

Of course some people are more creative. How about virtual geometric patterns. The cool thing is that you physically have to have been there.

Teddy Roosevelt would have loved this. As President, he was taken with long walks with visiting officals (who had to go along). At some point in the walk he would announce a return to the White House using the most direct method - often through shallow ponds which, in the Summer, were covered with a film of oil to control mosquitos.
Some people take their hobbies seriously. In rocketry one finds a range of activity that starts with model rocketry - the sort of things that one finds in hobby shops and seems to be a univeral activity with young boys. The next step up is a large step -- high powered rocketry. One now can spent thousands on a rocket and a launch may be an event halfway across the country in a place like Blackrock, NV. There are fairly serious people, but the critical components (like rocket motors) are purchased.
One fundamental difference between model and amateur rocketry is that flying eggs is considered sport for the former and bowling balls for the latter.

Moving up a level is amateur rocketry. Here nearly everything is homebrew and the level of technical proficiency is high (CalTech and MIT have groups of current students, professors and alumni) - eg - you find real rocket scientists. Several groups work with liquid fuels and a few groups have their eye on being first amateurs to orbit something. The Reaction Research Society is one of the more important groups.

And finally we have professional rocketry - the stuff NASA and the military do. There isn't a huge difference between the low end of the professionaland the high end of the amateur games
I've been fascinated with Alan Epstein's microengine program at MIT for some time. There isn't enough space to go into the deep coolness that they have provided, but one line of research deals with building tiny rocket motors using microelectronic construction techniques.
To call this research multidisciplinary is an understatement - this is a real liquid fuel rocket motor with turbopumps. Much has been written about this, so hunt around.

Finally - your tax dollars at work. All you can do is shake your head. Thanks for the tip Andrew.
