Tree roots that push up the pavement on MUPs.
Utility caps set below the road surface that act like really bad potholes.
People riding two abreast on the MUP when another rider is clearly approaching from the opposite direction.
People riding two abreast on the road when cars are stuck behind them long enough to start honking.
Passing on the right.
Young hotshots who have to pass no matter how much they scare the crap out of people.
Every flat tire I’ve ever had.
Body parts that wear out long before my legs do. Shoulder pain from bike riding? Really??
