Elk are frequent visitors to mountain towns in or near the Rockies. Don't attack except in breeding season, but most animals go nuts at that time. Moose can get spooked easily, I have seen one go through a tent camp site, getting tangled in tent ropes and bringing the tents down. Luckily no one got trampled. Usually they are little trouble if left alone, but in this case two children ran up to it. In the mountains on one of those occasional warm summer days in spring, I have had mountain sheep come up to the table where out lunch was spread, begging for a handout.
Wild animals should never be fed scraps; that encourages them to be bold, and also victims of cars on mountain roads.
