Daring Kitty, or is it dumb cat?

Sean's parents were here for the last two weeks. They drove in, in this really cool RV. After they unloaded they parked it in the back of the house, out of the way. As you can see from the first picture, it was close to the railing of the porch, which Einstein always sits on. So he decided to investigate.
He wandered around on the top of the RV for a while, then hopped back up on the porch when he was done. And every day after he figured out what was out there, he went back, thinking he was cool:)
