That is so funny!!!
Are you going to let him have the corn he planted, or are you going to eat it?
Wow! I just can`t get over the fact that chipmunks can make garden of their own!!
You could give him most of the corn he planted and keep some and then, when next year rolls around, you can give him corn again and see if he plants them again!!!! It like you have your own mini gardener!
