Yesterday, an oncoming older male jogger crossed over into the lane I was riding. I ride on the right side just like as if I was in an automobile. There is painted wording and arrows on the trail giving such instruction. I had seen him a few seconds earlier in 'his' lane so I put my eyes onto the scenery or something. We were the only ones at this location. Next thing I'm getting 'warned' and had to get on the 'wrong' side of the trail. As I went by I just said 'stay on the right' and left it at that. (Pun intended!) To me, that was weird and didn't make any sense. FWIW- I slow way down to pass when an individual group is on the path. I use it as a reason to sprint away! Because of the prevalence of ear buds and portable radios that even I can hear I'm less inclined to say 'I'm gonna pass'. I just creep by and let the FW talk.
