One of the advantages of having a teenager staying is that you do things you wouldn't normally do. We had my niece staying with us and so for the first time in my life I've been grass boarding. Yes, all that safety equipment IS necessary. My ribs are starting to recover!
We also went to the brine baths at Droitwich. It is as salt as the Dead Sea, and is supposed to be very good for bruising and muscle strain. A good place to go after my escapades on the grass board.
We had a motor boat on the Avon from Evesham. Working the locks was a challenge with painful ribs.
We also had an afternoon when the Young Farmers when they were lawn mower racing. They were very competitive and how they kept some of the machines going showed great engineering skills.
