Not strictly a matter of handicap access, but more particularly on the subject of hanidcap mobility:
A year ago, for Christmas, I bought LiK a "mobility scooter" specifically to help her to get around at the WVA Festival (Winfield). She has used it there for two years now, and it's been a great help for her. Quite likely, I'll be looking at getting one for myself before next year1, since the distances are substantial (relative to my mobilating capacity) between our campground, other campgrounds where the jamming takes place, and of course to the rarely visited grandstand area.
The first time we took it to the festival, I took it when I went down to get in line, so I had a couple of weeks for try-outs and adjustments. It made the trip from the campsite to the Walmart/Dillons area, and to a couple of hardware/lumber/auto part stores a couple of times, so maximum range - with the then new batteries - probably approximates the advertised 10 miles. A round-trip to the shopping areas I visited was close to 5 miles, with a lot of detours due to bad surfaces, and some remarkable hills that one doesn't noticed when driving through in an auto. (We noticed some "fade" the second year, but not enough to hurt her use within the camping areas.)
Her particular scooter is a "travel scooter" that breaks down for "easy transport(?)" in a typical automobile (if you're fairly clever about fitting things in). Unfortunately, it has the "small" (7") wheels, which make it extremely marginal on gravel roads or in rough grass. With its 1.5" ground clearance, a garden hose or heavy extension cord across a hard surfaced road (quite common at WVA) is an "impassible barrier" unless you can find a place off at the side of the road where the "cord" sinks in a bit.
I got her scooter at Pep Boys Auto Parts, for $600. Apparently identical ones, at the same price, can be "web ordered" from Walgreens, Sams, or Costco - among others.
An acquaintance at WVA the first year had one virtually identical to hers, through a medical supply outlet, paid by insurance/Medicare, that she recalled "was about $3,400."
For those with the insurance, there is probably a substantial benefit in having a reputable and local service place, and some "support" for the vehicle. Lin's has NONE. My phone call to the distributor got the information that "There used to be a guy in Hutchinson (70 miles) who worked on them some." The address they gave me was on a street that according to current maps NEVER EXISTED, and they didn't have a phone number.
Even at that, the difference in price seems a bit out of line.
There actually were a few minor differences between the two scooters, but for the most part none that would be significant if one had a parts manual for either. MOST NECESSARY SERVICE on either could be done by any reasonably competent shade tree mechanic, but there seems to be a deliberate conspiracy among "medical suppliers" to prevent any information on the details from being available to users.
Searching the web for circuitry details found nothing - except multiple warnings about dealers and their "maintenance scams." (Many of these were from UK sources.)
Comments would be of interest. (?)
1 Pep Boys now has a "garden cart" with electric power, using the same control box, transaxle, and batteries as Lin's scooter, with BIG WHEELS, for $190. I may put a boat seat and tiller on one of those.!!!
