Wandering is great. I've seen some of the coolest stuff while wandering.
One thing is great now days is to wander using Google Maps or Google Earth. Rather then take the time when it's short and potentially get myself into a time crunch I'll go home and scope out exactly where that road went, or if there is an alternate route form here-to-there and next time I can take it and see what it's like.
I was examining a common route I took in Google Maps satellite view and saw something strange, an apparent MUP like oval about 1/4 mile in diameter right smack dab in the middle of a neighborhood I cut through all the time. Hadn't a clue it was there. The next time I went up the long steep gravel drive to find it. No signs, all kept up, a 12' wide concrete oval with a small soccer field right in the middle of it and a few picnic tables by it. Not a clue who owns it or whether it's open to the public. The cities web site doesn't list it as a park. Never would of found it without looking on GM. I tore around it trying to see how fast I could go without a worry of hitting anyone or car traffic. I still visit it once in a while.
