While doing research for this blog, I came across a product and organization that I was not aware of. Horse carriages that are wheelchair accessible. I first saw one that was for sale and wondered if there were any more. Which is when I then learned about the United States Driving for the Disabled, Inc (USDFD). A non-profit that helps and promotes people with disabilities to experience horse carriage driving.
Ramp Option
The wheelchair accessible carriage I saw for sale was one that had a ramp like the ones pictured above. Where the ramp slides out from the rear. I understand that because of the height of the carriage, a ramp is going to be pretty steep. However I do feel pretty uneasy that there is no edge protection to prevent wheels from falling off the side. This would be easy to add and would not interfere with the sliding storage. But given the logistics, this option could work for some.
