I've always just used string to hang our sandwich boards (easier than doubling over duct tape). Cuzco always wears his sandwich boards very proudly. Here he is way back in 2005 helping me advertise my "Lake City Carriage Co." in the 4th of July Parade.
This was about one month after he lost his horn so his head was still in bandages. I covered it with a sporty blue bandana, but seeing as this was Independence Day, I maybe should have left it in view to invoke the famous Revolutionary War hero. But then again, it's good not to raise the ire of any animal rights enthusiasts in the crowd if you're trying to advertise a business!
The black horse is my now-gray Jet and the bay is his mother, Easter with Phil's sister riding her. I wanted to drive the carriage but since Jet was barely three and had only been pulling the carriage for a couple of months I decided it would be best not to put him in a crowded public situation where it would be hard to contain him if he spooked or did something "coltish". This was his first parade and he did an exhibition of standing on his hind legs about halfway through, so I was glad to be riding instead of driving. I drove the team and carriage with the county commissioners in it at the head of the 4th of July parade in 2006 when he was a bit better trained.
Cuzco became a Lake City celebrity when he lost that horn--everyone was inquiring into his well-being for months afterwards. He also was the hero of the kids and parents because he spent his 4th of July afternoons pulling children around the town park in his cart. We made good money those days. I loved having both a horse and goat carriage because it made my business a lot more versatile. I did horse carriage tours most days, but I used the goat cart during big celebrations because the blocked-off downtown square was too crowded and busy to safely maneuver a horse team and full-sized carriage. We'd have spent most of our time stopping to wait for people to cross the road. Cuzco and his cart, on the other hand, could weave in and out of the people and kids always have a great time honking the bulb horn at grown-ups who won't get out of the way.
