I SWEAR this sounds like a set up line for a joke, but I'm going to be a good questionland contributor, and not go there...

Have you called a tire shop like Les Schwab or somebody like that? Or stop by the local tire place and ask them if they can do it. If they can't help you, they may know of somebody who can. Apparently they can be taken out, but you can't put them back in, is all.

I would start by looking through the TriMet code and administrative rules at http://trimet.org/about/code. Keep in mind, too, that they've received a series of grant monies from the Transportation Security Administration (TSA).

Maybe you have an inner ear problem. Have you ever gotten your balance checked by a medical professional?

It's not about using muscles to resit the movement, keep them loose so you can go with the flow and ride it out.

Pretend that you're skiing and use your legs as shock absorbers. When it's going around a turn, lean to the inside like you're guiding it around.

Living life inside your own head can be fun.

I researched this a few years ago, and those signs do not apply after 7 p.m., even the 5 minutes spots. Park away!

Try craigslist… dinkus.

Who cares? - ride your bike.

If you can find a surface to lean causally against, even if you are barely touching it, you won't need those super muscles other people seem to have. If not you just need to "spread ' em" and anticipate stops and turns. The wider your stance is the better luck you will have and the less I'll have to stifle my laughter when I see you fall.

I have to side with the anti-Walmart crowd.

That corporation is equal parts sadness and evil, powered entirely by the tears of migrant workers, and forlorn baby kittens.

As for craigslist, that site is absolutely brilliant for finding anything. It has a far smaller "shady asshole" population than eBay, and by meeting a seller in person, you get to size them up pretty quickly. Plus, the prices and quality of items you can get from craigslist really can't be beat.

Yeah, there is the inherent risk that whatever you buy might be stolen, but in my experience, craigslist is no worse (and often better) than any other previously used item reseller in existence, including licensed businesses that operate on that model.

Obviously buyer beware, but craigslist has never let me down in the past.
