Thankfully, I learned the other way: I also moved the saddlebag back and forth, forgot that but had the pump. The puncture was a slow enough leak I could get about a mile before having to pump it back up, managed to hobble back to the car. Stopped on the drive home to buy one for each bike :)

Mine came with zip ties for that purpose. I don't see any way to actually run it to a bottle mount. Made it real easy to move it from bike to bike, too.

Nope, still a PITA, although much less of a PITA than unhooking the pump and using a gauge.

The narrower tires on the new bike require much higher pressure than the "thick" tires on the old one. They will also have to be checked much more frequently, the narrower they are, the more often they must be checked. Puncture resistant or not, under inflated tires are vulnerable to pinch flats. Since you don't actually know what caused your flat, you don't yet know if better tires will cure the problem

There are sometimes limits to how wide a tire you can install, and anti puncture protection layers cannot protect against pinch flats

It was in spring, summer, and fall.

I think what I am going to do is alternate between hybrid and mountain bike. On the paths with more debris and possible road hazards I will ride the mountain bike and on the paths that tend to be more clear from road hazards and fallen debris I will ride the hybrid. After a bad storm when most likely there will be a lot of fallen branches on bike path, I will ride the mountain bike.

I also will get some equipment to replace a flat just in case. I am assuming I could buy everything I need to replace a flat from the Trek store.

You really don't need to, and you need to figure out the cause of your last puncture. And besides, mountain bike tires get punctures, too. You might have just gotten lucky before. Learn how to deal with fixing a flat, consider upgrading your tires, check your tire pressure before each ride and top your tires off if the pressure is low and you should be fine. My only puncture last year was a freak thing. The valve stem sprung a leak at the base where the valve stem meets the tube, and that had nothing to do with anything other than maybe a manufacturing defect. The time before that was two years ago, when my rim strip slipped, exposing the tube to the sharp edges of the inside of the rim. Again, a freak thing that could happen to anyone, at any time.

I had that happen to me too and fixed it temporarily with some glue and a zip tie - but I was wondering if maybe it was caused by improper tube installation such that the stem is not centered in the rim and rubs against it?

Switch to Gatorskin tires. :D
