Please contact Coach Allen Nelson (12u SandGnats) if you're interested in purchasing a portable mound for your child, team, or rec departments. Prices are unbeatable. $575 for a portable mound is the lowest price around.
Nelson and Sons are also now offering batter up (picture included). Prices are $129 for youth size, and $139 for adult size. You should include adding this addition to your list of equipment.
