this is a nifty site.
Wildobs lets you upload the location of wildlife you find around North America (at least) with details about habitat, and mapped locations. I am going to explore the area near where I live, find out what's around at this time of year that I haven't yet noticed, and go look. It's a perfect "get outdoors now!" computer toy. (There's an associated iphone app, too. I don't see anything for my Treo yet.)
