Actually, Geocaching.com does NOT dictate the entire world of caches. Just the one's posted at that particular site. There are other sites with less stringent rules you can go post to. I wonder if having a cache in the science center is really going to bring more people there that wouldn't already go? I haven't done the GO-Busch cache or the City Museum Virtual because a cache is not enough incentive for me to go either place. If by chance I happen to be at either of those places, I might spend time doing a cache. But, even though I frequent the zoo, it took me several times to get all the caches there because my family wants to see the ZOO, not cache! :) They complain that we never go to a playground just to play anymore. There's always a cache involved. LOL) And actual caches are far more incentive to all of us (in my family) than virtuals, the kids love to trade. Figure out a way to make us do scavenger hunt in the Science center and then take data to find a cache in forest park or something like that. Or better yet, work with the science center and see if you can hide one IN the center. Maybe find clues with in the center to get the combination to a locker there? Just some suggestions. Jen
