Well, cool. I've been able to get close to a certain point, and then they tend to take off, which is fine. Actually, the larger they are, it seems, the less likely they are to move has been my experience.

Yeah, i don't know what the deal was the last time we went. The first time around, the weather was great, and that's been my experience the other places in Mexico we've gone, especially in the coastal areas. That time, though, you could take a shower towel off and be perspiring again before you got dressed. :) First time ever I've had trouble breathing because of humidity. Not fun.
