It's been a while since I've found the time to fly my drone. I passed the test a while ago after new laws were introduced in the UK for piloting a drone and haven't had the time or ideal conditions to get out and enjoy it!
The fruits are way too sour to eat raw. Best picked after a frost or prick them and soak them in gin to make a sloe gin. You can use them in sauces with apples, wines and jellies.
