Chances of the horses running across radio controlled vehicles while out on the trail are pretty darn low. However, both of my brothers and their wives race RC trucks, so I saw an opportunity to start desensitizing the horses to them. We live in paradise (just my opinion, but I love it here) and one of the things Jay and I want to do is host get-togethers frequently this summer. With a few acres to play on, we can easily run the RC trucks, play with dirt bikes or three-wheelers, throw knives, or shoot the crossbow.
Jay and I have shot the crossbow outside of the horses' pen before and they don't care. They didn't care much about the knife throwing either, but the RC trucks caused a bit of a ruckus.
At one point, a truck made its way into the pen (things happen when you allow a six year-old to drive), but as soon as the truck came to a stop both horses went up to sniff it. Monster, my youngest, managed to snatch it from the jaws of death just before Skeeter started pawing it. Thank God for quick reflexes and the ability to climb fence like The Flash, because I don't think I could afford to replace one if Skeeter had rolled it around trying to figure it out. Those trucks are made to withstand a certain amount of abuse, but I don't think 900# of abuse would be good for them.
We still have to get the three-wheeler up and running, along with the dirt bike, but so far, summer desensitizing seems to be going well.
Hay net update: the horses have slowed down on their hay intake, to only a bale a day. They're still killing the bale overnight, but not *starving* to death in the morning. Looks like Mom's not going to get our net.
