Sorry I didn't see this thread earlier. As you might guess, I live in Boulder, as well.
My next "local" diving will be in Santa Rosa, NM, in the third weekend in December. We will leave Thursday afternoon and arrive Thursday evening. We will dive Friday, Saturday, and Sunday, but not at the Blue Hole. We dive in nearby Rock Lake, which is roughly 8 times farther across than the Blue Hole and about 3-4 times deeper, depending upon where you are in it. The problem with it is that it is on private property, and only a handful of people are allowed in. These people are all instructors, and they are themselves allowed to choose who they will allow to join them.
It is advanced diving, and the owner only allows AOW or above in the lake. In practice, it is primarily for technical instruction or fun diving for those with the appropriate training. The environment is much more primitive, natural, and fragile than the Blue Hole, and the instructors who are allowed there will generally be picky about who can join them.
According to your profile, you are a GUE Level 1 diver. You will fit right in with us and will certainly be welcome without any further questions. We are a UTD group, so our training will be very similar.
Our next planned dive after that is the Oriskany in January. Some of us will be driving down and others will be flying.
If you are interested, let me know. I can get you hooked up with helium and everything else you might want.
