so...my question is this: what's the name of that little tool/device that you roll on a map and it gives you the mileage? or should i just use string? the problem with string is that i have two seperate, two-sided maps already, and i don't think string will stay put with my cat around.

so, yeah, what's the name of the tool, and what kind of store would have one?

oh yeah, i could've dreamed that such a thing exists, but i'm pretty sure that it does.
