The posted coordinates are for one of NH's finest covered bridges. You are about to visit the Rowell's Covered Bridge in West Hopkinton, NH. No area around the bridge seemed suitable for a good quality cache hide, so we placed the final less than a mile away.
Yes, you'll have to drive after getting your info.
The final is at 43 AA.BCC 071 45.DDE
AA= The posted speed limit for vehicles going over the bridge.
B = The tallest vehicle that can fit in the bridge is __ft and 9 inches
CC= The number of boards on the floor times 2 plus 8. (yes, that includes the ones under the support beams.)

Checksum : North will equal 23 West will equal 29
You can park on either side of the bridge, but you will have to walk the length of it to count the X's. There is no sidewalk, so be extra careful with children.
