3 LEGGED BEER RACE

Some competitors for the annual three-legged beer race (a half-pint to be consumed at intervals along the route).
Unfortunately we heard that the race competition has been cancelled, but the competitors are still running for the beer.
The competitors were obviously all ready to go at 7pm; I wonder what happened. 

It rained at about 7pm and now,7:50pm, we have a rainbow. (Extra)
