Expect the unexpected.

#3. If you have any dependency on any type of mobility device (i.e. wheelchair, walker, crutches, cane, or anything else I might have missed) you should practice the boyscout motto: Always be prepared. Even if it is just having printed out a list of medical supply dealers near your destination that can do repairs.

I have learned this the hard way as on not one but two separate occasions I have had wheelchair issues. My last one was a simple flat tire. Simple if you are at home with your vehicle in the driveway and your spare chair in the garage. Not so simple when you are getting ready to go see the fireworks and have a nice meal. Luckily I was at a great and amenable hotel who made every effort to assist me in-house trying to inflate my deflated tire. When that failed they quickly looked up a repair place and hooked me up with one of the park,s loaners (which was shall we say a love seat on wheels--I only if I had a picture to show you, too funny).

This was the point where I said never again will I be stuck in a horseless chariot as my small, zippy chair gets a chance to see California without me. I now travel with 2 spare inner tubes, a tire-changing kit (available at a local bike shop), compressed air tire inflator (have you tried to fully inflate an inner tube lately? much more difficult than you would think), a few Allen wrenches, a screwdriver, replacement screws (if known what sizes), and a travel sewing kit. It may seem like overkill to have all of that taking up valuable luggage real estate but if you need it you will feel like a super-genius for having it (if only those Wile E. Coyote cartoons were real -- you could just dial Acme and in 5 seconds it would arrive).

Just remember one thing I have learned over the years. If it can happen it will, and usually at the most inopportune moment. With just a little preparation you can combat the gremlins that want to wreck your vacation.
