Honestly who steals a mans bike!? Especially a hardened adventure bike. It's obviously your only major possession. What a son of a bitch! I'd probably lose it if I came out and found my bike missing. And I mean lose it in the "check him into the nut house" kinda way. What a shitty way to start the European leg of the trip. I hope this doesn't end the trip for you, and I'm sure you can find a decent bike a bit of cash. Might mean forgoing some of the drinking on the rest of the trip.
Good luck and I'll be checking on ya regularly.
