I ended up behind a R* and 2 HD's on my way home from work today, Followed them from Rogers, Ar. to Gateway where I turned off and they headed on toward Eureka Springs. Weren't a very friendly trio. Was behind them for about 18 miles and one of them kept looking back at me like I wasn't supposed to be occupying asphalt with them. I nodded at him a couple times when he would turn around and glare at me but he didn't acknowledge that I had done anything at all.
I don't think it really matters what horse your saddle is on. Not everyone is as friendly as we would like.
If I would have had a good safe section of road I would have just blown on by and left them back there.
