Ya, they are pretty big. I had one wonder into my camp once while I was a little ways away fishing in the creek. As he walked around my tent I just hoped he didn't get tangled up in the ropes. In some areas moose are a bigger concern to me than bears. But, also probably more apt to spook off with noise. One of my brothers spend a couple hous on top of a big rock with a couple moose around it. He didn't think his fly rod would be that much help.
