>>783464i spent 2 months traveling around europe when i was 17 with just my best friend. and no, mommy and daddy didn't pay. and now i regularly go on deep backcountry backpacking and climbing trips in the sierra. so if i had the inclination to bike across the u.s. i could, but i have no interest.
if you're for real my best advice is put this off for a couple months or a year and start with local biking trips that take 2-4 days. you'll learn what you need pretty quickly, but you won't be stranded in assfuck nowhere, or have the emotional refusal to accept failure that leads to injury or death. seriously. have you even ever spent a night /out/?
