Well, now that you mention it, have you ever been to the Blue Hole in Santa Rosa, NM? We've got a group meeting down there at the end of April. Looks like several people from this SD.com are going, plus a whole group of students from Boulder. See this thread: Dive the Turn Blue Hole for more info. It's a 7-hr drive from Boulder, but plenty of people are driving from here. If you want to post anything about that trip, be sure to post it on that thread rather than here.I'm almost always up for diving depending on the site. Have no desire to dive Carter Lake again.
I've never gone diving in Carter Lake or anywhere else besides a swimming pool in our great landlocked state. Carter Lake was too cold and murky, I s'pose?
