Matt did they give you any bike entry papers in Desaguadero on the Bolivian side?

Cause when I got to Villazon, the Bolivia - Argentina border, I was told I should have some sort of an entry document from Desaguadero for my bike. I told them nobody paid any attention to the bike there and it´s not my fault the Desaguadero border police couldn´t be bothered.
In Villazon, they first said they should impound my bike as I seemed to have entered Bolivia íllegally´; I went berserk on them so they just let me pass to Argentina and pretend I never was in Bolivia on a bike:):) on the Argentine side, I got issued bike entry papers (same on Argentine-Chilean border etc). No probs ever since.

Guess Desaguadero´s just EVIL:ban:

This exact same thing just happened to me today at desaguadero. With a Peruvian registered bike in my name, they wouldn't let me through without completing the process you describe. Instead, I'm going to try and enter through Chile at Tacna. The Aduana people said its possible there.
