Folks living nearby told me there's a trail off Raccoon Lane going somewhere useful.

This is a mess. Resurvey the end of Mandus Olson, and paths vs driveways vs the stream and the road itself.

Horse trail continues all round the park according to Parks & Rec maps.

Make a hole in wood for the parking lot.

Is this really part of Albertson Road, or is that the road to its south?

Could be a path east here. Looks like public ROW.

Could be path west here. Looks like a public ROW.

Route of the Creek is probably wrong.
