Texass riders

What is it with you guys? Never a warning when passing or even a "Hello". Just like this morning commuting to work with my messenger bag slung over my back. I slowed to allow a motorist to make their unexpected right turn across my path and lo and behold a TX cyclist, non commuter, blows by me on the left. Just irritated me. So I caught him and drafted until the red light a mile up the road when I cruised up and sarcastically said "Hello". Caught him off guard and he just waved. Maybe there is hope for them. I always preach safety and courtesy to fellow riders. Just don't want to ride with jerks.
