I was asked to bring a guitar with me when I went to Argentina the last time. I thought about that for all of 3 seconds before saying "No!"
I did not relish the idea of traveling with a guitar for 2 weeks to the places we were going, nor did I think that carrying it on the several planes and through the airports and security in foreign countries sounded like a fun idea.
Instead, having been to Argentina before, and knowing there were a number of musicians there whose guitars I could borrow that were already set up on stage..... I simply asked that one be provided for me as the need arose.
Everything worked out perfectly and there was never a time that I didn't have a guitar when I needed one. One fellow there even offered to give me a guitar to carry with me, a spare that he had, for my duration in country. I did not need it because every place we went had a stage setup ready to roll.
