Where can I get some? I want to set up pony rides for a fundraiser for my club, but I don't want the kids to ride without helmets because we're using large ponies and a horse (13h-15.1h). The closest tack shop is an hour away and TSC doesn't supply disinfectant. I want something that's strong enough to prevent spreading lice, but not harmful to younger kids. We haven't set up the date yet, or even agreed on doing pony rides, but I'd like to know where I can get some for when we do, if we do. Even if we don't, It's always good to have around. Any suggestions? I'd like to stay cheap since we're probably going to have to buy 2-3 bottles if they're small.
