21 is a good age... I'm an old fart @ 33... Ah well, the bank account IS better for sure...! I travelled for a year and a half when I was 22.
US, Canada, New Sealand, Australia, Indonesia, Singapore, Malaysia, Thailand, Cambodia, Laos, Venezuela, Colombia, Equador, Peru, Bolivia, Brazil.. Took me untill last year to pay that off, LOL ! But was WELL worth it...
But I had to wait untill I was 30 to buy a Firebird.
