I was on my way home from work today on the hwy with two south bound lanes cruising in my spyder at about 75 (in a 70). I was on the car because the GSXR is in the hospital. Anyway I came upon about 15 guys on cruisers, they looked to be in a club because they were all hearing the same leather jacket with some patches on the back I didn't bother to read. Anyway they were almost all in the fast lane going about 70 and making everyone pass them on the right. As I moved to the right to pass the group I notice one bike in the slow lane so they've effectively taken up the whole freeway. As I approached the lead rider motioned for that rider to move over and he did before I had to hit the brakes. That was nice so I waved thanks as I passed them on the right. So, the question is: Why do they do that????? Isn't slower traffic supposed to be in the right lane? It's not a huge deal, just very slightly annoying. Maybe some of you guys who ride in huge packs might enlighten me.
