Had three in two days last month and hope that's it for a while.
Rode on my city bike the last two days, about 15 miles a day around town. I'm doing a brake job on the pickup so I can't get my bike the the grave yard where I ride. If I try to ride to there I may end up in a grave. Temp's are in the hi 90's so I'll try to finish the brakes tonight when it's a little cooler.
