Located off of a brand new section of rails-to-trails in the city of Saint Louis Park. There was only a short run of track here that needed to be converted to connect two much longer lengths of paved trails together.
The coordinates above will take you to the "wall". It's a pint size tupperware container with a few trinkets and a log book inside.
The best parking would be at:
Take highway 100 to highway 7, head east. Take a right at the first light, Beltline Blvd. Take your first left after the railroad tracks, which is Park Glen Rd. Follow your GPS from there as far as you can drive.
