Equinventions This is a monthly Column featuring new inventions and gadgets related to horses. We invite your submissions and suggestions. If you travel with horses and use the front stall in your trailer to haul hay, lawn chairs, etc., there is nothing more frustrating than to arrive and unload to find that urine and manure have messed up the front stall or the tack area. To solve this problem Tammy Coffman developed a product called Blockade, in September 2009. It looks like a stuffed sock, similar to what you would put at the base of a door to stop a draft. You can secure the socks with Velcro, or push them against the wall of the trailer, to stop urine from flowing across the trailer. The cost is $24.00 for the stud stall and tack stall set; or $12.00 for the tack stall plus shipping.
