Gobes: you just made me curious. That cd be a dialectal thing... I know for a fact that montar is used... perhaps just in Spain and andar may be more widespread in Latin America. Google has 240000 for montar 340000 for andar which surprised me as I've never heard andar...

Weird.

Tomorrow I'll ask a Spanish girl at the interpreter school (I have an MA in Spanish and I'm a Hungarian/English/Spanish interpreter but Spanish is my 3rd language... And I suck at colloquial Spanish.)
