>>True, but this depends greatly on your equipment.<<

I know such equipment /exists/, but that's about it.

Its more...people can't slap a one-size-fits-solution on thus and say 'yay, fixed!'

>>A palanquin is exceptional because the platform can be equipped either for seated or recumbent travel. <<

I actually did not know this; palanquins are not local to my area and my first mental image is the palanquins Azula and Zuko use in ATLA, which are a sit-upright-no-chair style.

Also, semirelated, I recall the cover of this book* had a picture of a stretcher with a sunshade (designed for longish transport where cars might not be an option.)

>>Transferability varies, though.<<

That is a consideration, but I was also thinking of moving the /equipment/, not just the person.

I think I recall a conversation I once had with someone who drove her wheelchair-bound grandmother around, but was running into problems because the sporty car didn't have a lot of room to put the folded-up wheelchair. And you kind of need the wheelchair to get around at the store...

I myself have tied a folded wheelchair to a bike rack. (Doesn't do much good to drive someone home if their gear stays at the office.)

I know someone else for whom 'spend the night' involves a variety of machines and mechanical contraptions; conveying these via anything but car (or possibly covered wagon) would be nigh-impossible/impractical.

>>It can work as one of several options though. <<

This story taught me two things:

1) Clarify /every single exhausting non-standard requirement/ when you travel. /Do not/ allow yourself to be dismissed or patronized. (Also, a list* is very helpful.)
*List may include door widths, height of the gap under the bed (I am not kidding), layout of handicapped parking (some people need extra space to unload from a wheelchair van with a ramp)...

2) If a customer/client asks about wheelchair-accessable, or nut-free, or whatever /clarify that you ate taliking about the same thing/.

>>These should be freely available at events, resorts, parks, etc. to maximize accessibility. <<

The artsy fair at my college did this as standard; students got volunteer hours for carrying the setup stuff and vendors were very impressed. (I also went around in historical costume one year. Fun times...)

>>Many jobs require workers to lift 50 pounds, ... <<

Lifting once, easy. Lifting repeatedly, or carrying a distance, very hard.

>>L-America has dwindled to a few tattered remnants like bellhops at hotels. <<

I was concerned that 'muscle power' would once again translate to 'Relatives will do it for free. Not my problem.'

I have no expectation that L-America will start hiring hiking porters.* (To be fair, some airports seem to do a decent job, but I suspect their gofers have several different jobs instead of being exclusively porters.)

*Hmm... in-a-group porters might be a good job for immigrants who don't speak much of the local language. You wouldn't neccesarily need to be chatty, just strong and decently up-to-date on local 'polite deference to the customer' ettiquite. If you can get one person who us decently billingual (teenager at first job, maybe?) all the better!

>>Prevailingly true, but consider the nature of the trail. <<

Just as you can't assume everyone on the trail can walk, or walk for long distances, one shouldn't assume that every trail can be wheeled on.

Mindful consideration of your specific circumstances is needed!

How much damage will wheels or motor vehicles cause? What are the safety issues, both for and aginst? How many people who want to use the trail will be unable to with XYZ restrictions? Is there any way to reduce that last number without increasing damage or reducing safety?

Then pick the most workable solution, which could be anything from vehicle tours to video walks to palanquins. :)
