Sorry to see that a fellow soldier has to give up a bike, and also that there will one less Triumph rider on Hood.
But I do understand the importance and expense of a dog. Mine swallowed a pair of Vicodin and that cost me a pretty penny let me tell you. I should add, have you considered pet insurance? After that incident I got a policy just in case.
Anyway, I would add in addition to Craigslist, see about putting up a flyer at Kay's Motorcycle Mania - it's in Nolanville just off 190; take the TX-439 Spur/Nolanville exit, make a right at the stop sign (coming from Killeen) and it's just on the other side of the gas station.
If I wasn't deployed myself, I'd try to put a ride together to fund the surgery and save the bike.
Anyway, good luck - oh and I'll ask around over here, I know a few guys in my unit looking to get a bike when we get home.
