I'm not at all suggesting that the climbers here are jerks, as I mentioned in my original post most of the people we met were super friendly. I know it's a busy crag too but I've been to quite a few other extremely popular climbing areas across the country and never come close to having multiple unfriendly encounters in one weekend.
I also don't want to say that I'd never go back. I'm probably still just a little frustrated at the whole situation. Having this many issues in one weekend kind of turns me off to the area when I can go somewhere where I don't have to worry about my stuff every second I'm climbing. But like I said, maybe we just got unlucky for our first visit.
The thieving happened on Saturday sometime between 6-9 PM. It was fairly empty at the time. It must have been climbers because I found the marking tape from the gear peeled off next to my pack... not sure if meth heads care too much about marked gear.
EDIT: The pieces were brand new Metolius off-set master cams yellow/orange with an orange biner and orange/red with a red biner.
