Squirrel!

This year the local squirrel population has got even more local, with one pair building a dray (?) in the tree at the foot of our garden.
The tree is actually next door and it's a nuisance as it drops seeds and produces ash trees all over our garden.
If you get them in the first year, they pull up easily, but after 3 years, it needs a garden fork to free the roots before they will pull.
