A couple of weeks ago we went to Stone Mountain, Georgia to play in the snow. They have a snow play area and a snow tubing area.
Don't let the pictures fool you, it was 60 degrees the day we were there...and that was fine with me. :)
This is the "kiddie" tubing area. It was a good warm up for Nate.
They have a moving sidewalk that takes you up to the tubing lanes.
If you live in our area and your kids are over 36 inches tall, you should definitely check out Snow Mountain.
