Many people travel, but exploring is much harder.
If you got the chance to do one of these 3 things for free, which would you choose? a) underwater cave diving, b) climbing a mountain, or c) traversing the rainforest.
FUN BONUS! If you couldn’t die or be injured on the trip, would you make the same choice??
actually, not dying didn’t enter my mind, so my choice is the same anyway. i’d choose the rainforest. i’ve been in the temperate rainforest in northwestern u.s., but i’d love to have a go at the tropical rainforest. i guess my caveat would be that i wouldn’t feel the heat!
