Hi, Rusty!
The  family has now  gone home...we have all had a lovely time together!
BB was telling me all about his charity run.
I had not realised that it was an obstacle race!   
They had to go up scramble nets , and crawl under very low poles, jump over water….........etcetera!
He has got a very distinctive medal!
I have just watched the last Brush dancing video that you sent ......very nifty!
Ah,  it is nice to come back to the computer and find out that I had it right all along about the knot-tying ceremony! 
I knew that I had  read about it somewhere!
I think the  tradition  actually went back to Roman times?
Have you been watching The Thousand Guineas?
I have no idea of the race times?
