In regards to the letter concerning the Spruce Railroad Trail, I would be happy to loan the writer my manual wheelchair for a quick roll up the trail.
I’m fairly sure that within your first 50 feet, if you able to go that far, you’ll possibly might want to re-evaluate your hypothesis.
You also might want to take a closer look at the 4-inch wheels on the front of most wheelchairs today.
Or possibly it will become painfully obvious to you within that first 50 feet.
Pavement with speed bumps, yes.
Fine basalt (sand) without speed bumps, no.
