Even a rainy day can be a good one for a motorcycle. True story:
I was 17 (1970) when I got my first dirt bike, a Honda SL100, mini thumper. I did a few 100 mile trail rides then decided to race scrambles and motocross. So the lights speedo horn mirror came off, and knobbies, Konis, big back sprocket, cam, 21" front wheel went on. I wasn't very good or fast, but it was a blast, and I built riding skills that still help me today when the chips are down.
Anyway, it's Sunday (1971) at Hadley scrambles, nice day good turnout when a BIG storm comes through, chasing many riders away. I stayed for the races, heat and main, slow going in the deep mud, but I made it to the finish line, packed up and went on my way.
A couple days later, my Mom is waiting for me when I got home after work. She tells me "A man stopped here today, he was riding a big Harley. He asked if you lived here, when I said yes, he left something for you". I didn't know what I had forgotten, when I went in the the house there is a two foot tall shiny trophy sitting on the counter. I got 3rd place, out of four riders. That's the only trophy I ever got for dirt bike racing, I still have it.
So even if the weekend was a rainy bust, somebody earned the trophy and he has a smile on!
