Obviously there's a range of spending, both at home and on tour. Let's try to respect each other, whether we agree or not.
Harutz, you are new to this forum, we try to be a little nicer here than other places, even other places on bikeforums. I'm trying to give you the benefit of the doubt here, but you're coming across as pretty judgmental and intorlerent. Maybe chill a little?
I really also do want to see specifically how to eat on $20 a week on tour. I wouldn't mind reducing my costs. I'd be happy to learn from you rather than be scolded.
