My 6 year old wants to start snow boarding. He can already cross country, and alpine ski. Might pick up a cheap'n'nasty kids snowboard package for him. There's a small but decent resort less 3/4 hours drive from our house. Now that my 3 year old is getting into skiing we'll probably be there all the time over winter.
I had planned on getting a touring package I could also use on the resorts. Probably where the smart money would go.
Ended up with a heavy powder package. That doubt I could walk for more than an hour with. Darn my powder addiction. Gonna be fun though.
If you're interested I might have some stuff from when I was that age, definitely have a board.
