Well, I coughed up the $30 and became a GeoCaching Premium Member, and, in addition to the satisfaction of helping this free service keep running, it appears that there are indeed really cool benefits already. First of all, I can do the sort of searches that I have wanted to do all along (search by difficulty, cache type, and radius, and have the results sent to me as a Easy-GPS file every week, so that I can just upload it to my GPSr). But, more importantly, they seem to be very open to suggestions of other member services, and I have a few suggestions.
Anyways, we have three caches lined up to look for today, so we’ll see how it goes.
