As a fairly new participate I'll say it seems most here talking about the hikes and "bad micros" must live in areas where trails and woods are not too far away. For those of us that live in a more urban environment, finding the micros can still be fun. Eventually I may be willing to make a day of it by driving a few hours to a more wild spot but at the moment I can't.
Also, while micros may not be the MOST exciting find, their small size definitely makes you search which I think is part of the fun.
I think most people leave because as people and especially as we get older we try to fit so much into our lives. Right now, I work full time and go to school full time and am still able to fill a few hours every Saturday with the kids finding micros in the city. I have plenty of other interests that I don't participate it, but hope one day I'll be able to.
Finally, I look forward to a time I live somewhere that has hills, mountains, trails, etc! (Tampa bay, FL ain't exactly a hilly place! The only hills are actually drained swamps!)
