On the table.
Or anywhere, really.
A few times as of late he's made it almost all the way over the gate that we put in the doorway. And Monday night at Grandpa & Grandma's house, he climbed into the tub while wearing his fleecy footed pajamas (and then started crying loudly because he got wet).
Today when we got home from school, we had our usual "game" in the car. It goes like this: I unstrap him from his carseat and he climbs over to the opposite side of the seat from me. I close the door and walk around the back of the car to the other door. While I do that he climbs back over his seat to the first door. And then we just keep doing this over and over. And over. And over. Lately he's also climbed up by the rear window and down to the floorboard.
When he finally stopped playing the game (because I grabbed him and dragged him out of the car), we made it to the deck. Then he was running all over the place. Then HE CLIMBED UP THE DECK RAILING. He was about to stand on the banister thingy!
Excellent.
