I was riding to work along the Alexandra pde today when I noticed a large group of riders. About 15 of them, mostly touring bikes, a couple of supersports; many were riding 2-up. They were maintaining an organized staggered column and were heading east. I followed them down the eastern freeway till the chandler highway exit(I get off the freeway there and ride down the Princess st to get to work). I wonder if anyone here knows about this ride? Clearly, it was an organized thing and I'm kinda curious to know who those guys were.
