Segway-like devices for disabled in national parks
 

I'm new here, so probably most of y'all already know this, but the U. S. Parks Service issues by mail an "Access Pass," that will allow you to use Segway-like devices in many places the general public cannot. They will also get you in free, which could be a big deal, now that the current administration wants to charge as much as $70 for admission to the most popular parks.
The passes are "available to U.S. citizens or permanent residents of the United States that have been medically determined to have a permanent disability (does not have to be a 100% disability) - that provides admittance to more than 2,000 recreation sites managed by five Federal agencies."
Details and the application can be found here:
