Singlespeed & Fixed Gear - Any reason not to?

So here I am in Chicago and the way things are going now I think I'll pretty much be going from here straight to Tokyo in a year or so with nary an inch of singletrack anywhere along the way. And so I'm thinking of converting my Trek MTB to a city-oriented singlespeed. Get a new rear wheel built, get me a chain tensioner, throw on some Armadillos, paint the thing black, and go. If its trail days are fundamentally over for at least the next 4-5 years (assuming it doesn't die or get stolen in the mean time), is there really any reason not to do this? I'm thinking no, but could use some outside opinions.

nope. do it.

Ok. It's a go.

Wow, one response and you're on it.

That makes you either a "yes" man or an easy sell.

I see no reason not to be easy when I want it.

I'll leave this one alone.

Oh come on - it was a perfect set up. I'm disappointed now. :(

OK, skitbra doesn't like to leave people in need:

You ****!

Skitbra is turning into a smartass lately. Definitely a good thing.

Now I feel all warm, fuzzy, and ****-like. Thanks. :)

It must be from hanging out with 165. I can just imagine 165 showing skitbra how to cane the kiddies to keep them in line.

yes, exactly. <mumbles...>
Hey MKRG - didja get the zine copy yet?

yes. Thank you very much. How did you know I am an Esquire the III? I've been working so hard to not let that out!

your pimp that used to send you to Lincoln Park to coddle all the lonely, ugly trixies told me.

Hey man! I had to pay the bills!

What brings you to sunny Tokyo?

Did somebody say, "cane"? Oh, goody!

Enjoy it now, for the fires of hell will be apon you soon.
