Yep the lighter mornings and evenings mean folk are starting to realise that they are not alone.
Best thing thing is to show willing and fit in as much as you can in the next few weeks after . Even cream off the easy burrows so you get decent numbers to show the landowner you know what you are doing . Then explain that next Autumn you will (with his hopefully continuing permission ) try to get round in a more systematic manner and take in the difficult areas a s well.
Good luck and well done with the permission .
