I've been using online mapping services to see routes from my doorstep to locations on the otherside of the continent.
It's wild. Theres a direct pathed route from your house to almost literally anywhere.

I never leave my neighborhood irl though. Anyone just get on a bike, fill up on snacks, and just go in one direction until sundown?
Also, tips on pooping when out? You could find a store bathroom, but outside of towns, you'll have to hide off the road and do it on private property.
