The folks at opencaching.us are peeved at Garmin for stealing their name.
IRBH--I've got a few to publish on the new site. I'm experimenting as well. These will be new caches that have been rejected or cannot be published on GC.com. I'm curious if they'll get hits.
And Kevin--I appreciate the proximity rule. Even I would try to not go overboard. For example, I thought about submitting a cache for publication on OC, but thought, "No, that's too close to this cache here" even though it's a good hiding spot. And I have been sharply stung by finding the wrong cache before, so I know firsthand how it hurts. One thing the new cache listing site has going for it is that you can rate caches. If it is at a bad location, I imagine the CO will hear about it.
