Glen lives at the north end of town (you will find him just after the town sign). Glenda, however, lives at the south end. Glenda will give you a clue, and parking coordinates, however, visiting Glen first would be less frustrating.

Glen was barking up the wrong tree again.
Glen is at N56 05.716 W5 07.036

Glenda's magnetism became a barrier, so she ordered more in the post.
Glenda is at N56 00.504 W5 12.788
You will find a small lay-by to stop at both Glen and Glenda's coordinates.
