Car rental insurance policies (technically not actually insurance, but a fee you’re paying to offset any damage you cause) rank high among the western world’s great rip-offs.

If you're at least 62 years old, you can score a $10 lifetime pass to America's federal parks and recreational lands. But act quickly because fees are about to jump.
