A while ago I was looking at the map of greenspaces around Shrewsbury and thought I must be able to make a nice loop from my home in Frankwell and visit some of these. By the time I actually got around to it I had a nice stash of cache materials so filled my backpack to make a day of it. 
It was a cloudy day in the woods so GPS was very bouncy, something I noticed was there there weren't any bird boxes?
