Alton has a free sand pile as well, limit 2 buckets however most that pick-up sand can't count very well
While at the sand pile a while ago I talked to a guy that had a receiver hitch spreader on the back of his truck. As I have a Tundra with towing package I asked him about it. He said that you can't use the sand that we were loading into our buckets. The 12V drive motor is not powerful enough. You have to use the tubes of dry sand that you can buy at Lowe's. At least that was his experience.
Thanks for the suggestions.
