Nope, wikipedia is hardly a reliable or authoritative source of information, as say compared to a typical line of bs from a troll using a clever handle on AP....? Tortoise's clearly have more sense than most AP trolls.

Have you ever watched what happens when a tortoise tries to climb over a rail? So they'll probably do just fine with those tunnels, just like they do with the culverts...

Cute critters always make for much more emotional EIS's in my experience. Especially to those who are "committed" to fighting things like UP's planned devious evil attempts to create a massive tortoise extermination program....
