Something like the one in this youtube clip?

BTW I just picked it at random since it showed the plane pretty clearly.
Yeah it was just like that, just the one I was in was a little bit bigger. You can see in the video that the plane was doing the same thing that the one I was in was doing, picking up & dropping off people onto cabins on a lake that you can only get to by pontoon plane.
It's a lot of fun going on a trip like that, the cabins we stayed at were up in Canada and we had no running water, no electricity, and no plumbing, so you used an outhouse, it was just really beautiful up there, no pollution, you drank the water right out of the lake. Only bad thing is if something happens like an accident you have no way of calling for help, just every couple days the owner of the place would fly in to check on us, and take out any bears, or fish we would want mounted. We've gone about 4 times.
