I wasn't really under it but there was a lot of water splashing off and getting us wet. At Yosemite later there was a bus that took to much time at each stop and we had to make 8 stops to get to the hotel. There were also some deer that were so close that we could have petted them but that might be illegal. --- That was cute until the dude lost his hand and the chick cut off her's. That was freaky bro.
You make each layer a different picture, then save as a .gif, it should ask if you want to merge the layers or to save as an animation.
