OK, I know you baggers have stereo systems and such but I'm on a stripped bike and I like listenin to music. I've got a pair of Oakley Thump Pros ... these are like iPods except they are shades with a built in mp3 player. My ? is are they legal to ride with? I completely understand about "distractions" and such but are they legal? Basically, can you listen to an iPod and ride (anywhere, but in Michigan specifically)
