The tricky ones are coming thick and fast now.
This is a little puzzler for you to solve.
The key for the padlock is inside the cache
All you have to do is work out how to get it out and undo the lock.
You will need a thin tool to solve this.
PLEASE, IF YOU BREAK ANYTHING WILL YOU MEND IT BEFORE YOU LEAVE.
Also you should only need to move one stone from the seat to find the cache.
Use your eyes before you move anything and leave it so that is can be spotted without moving stones but is still hidden from the front.
Another letter value, This Hawthorne has F thick trunks going into the ground, if you are not sure of this number please use the checker in the final cache.
Uphill now to the road.
