I've seen them while climbing at Pinnacles. They are pretty awesome to see flying, but I like watching birds fly.
As for the lead ban, I've read 3 papers about the lead ban and the how it affects the condors. Two of those papers showed (within a reasonable doubt in my opinion) that hunting season coincided with condors ingesting lead and dying.
While I fully believe that when I shoot an animal, my bullet goes in one side and out the other (mostly because of the animals I've shot, that's what happened), I won't deny (without proof) what I've read from other scientific journals. So, at this point I'm happy to use non-lead ammo in the condor territory.
