sometimes for a straight line a compass works just adjust the legs to a scale that make it walk

Lay out a string along the highway, mark off the two points, measure the distance between the points. Then use unit conversion.

we mark it along the side of a piece of paper and put that next to the scale

Yes, that's what you would do for a quadrangle. Everyone else is talking about highway maps though.

Yeah string method is the best method for something that isn't reasonably straight. We had a big wad of string for regionals but we didn't need it cause we didn't use any quadrangles at regionals.

Yeah, you really need the string for the competition. The not-straight mileage is important, but you also need it for stream gradient.

And Starpug, you didn't have any quadrangles at regionals?

Nope only a huge California Highway map

We got a quad and a highway map. The test told us to take a "road trip".

Which non nats test doesn't

Lol, they usually come up with a road trip on tests. Starpug, did you also have a map drawing or was all they gave you a highway map?
