Colorado Parks and Wildlife (CPW) requires fisherman in the state to purchase a fishing license to drop a line in the state's lakes, rivers, and streams. You can earn that fee and more back by fishing in Green Mountain Reservoir.
Why did the elk cross the road? To get to the other side, of course. The joke is silly, but for Colorado big game animals it's the truth. It's also dangerous for motorists as this crossing can happen without warning.
