Different environments, different exposures.

There's a restaurant I enjoy where on a good day in the right time of year you can easily see dolphins and whales from your table. Doesn't happen when the 2-stroke noise level is present.

I'll freely admit I've been on a dirt bike more than once. Conceptually similar, but I have no desire to experience it again. I walk, or swim, and enjoy the experience rather than machine stimulated adrenalin.

What sucks is that you now have me talking like a tree-hugger. :)
