one time me and a buddy got caught stealth camping at dawn by the automatic sprinklers in the lawn we camped on. oh, and that one time by park rangers near the road in the Teton National Park.

Drab tarps, keep a low profile, cover the bikes, and you can hide a lot of places.

international travel would require knowledge of local laws AND customs. Some countries it would be best not to hide at all but inculcate yourself or look for a roadhouse. Adding rebels or lawless maruaders into the mix would surely up the ante in safe planning.
