Sorry I should have posted this waaaaaay earlier (In my defence I only found out about it on Wednesday!)
Anyway, there's an open group of folk meeting up tomorrow morning, 11-1330 for an early spring clean of the path. Meeting at the Easter Road end of the path. Council are providing bags, gloves, pickers etc.

There will also be a bit of species identification if there's anything interesting growing or living along the route. Ending at Lochend Park. I can bore anyone with a bit of local history if required.
