The climbs are short and some weren't that great, but some others were pretty good and a less-than-average day of climbing is still better than not climbing. Anyways, back on Topic! =)
I hear that. Certainly not a horrible place to go for some winter craggin' either, as it gets good sun. I guess the last few times I've been there, I just had a shitty time (similar to your post) so I am jaded.
My opinion on the topic is; when you are doing something as inherently dangerous as rock climbing, it's everyone's responsibility to be safe and communicative. No exceptions. In this scenario, the TR party should have definitely taken more caution when setting up.
Also, when a rock is dropped in any circumstance, it is LAW to yell, "rock! rock! rock!" until it has hit the ground. This is as important as any and all other climbing rules and should be practiced as such.
