I came through in mid May at night. Looked back and saw what I thought were a bunch of lights
on a bridge. Looked back several minutes later and realized it was a composite tug pushing. And overtaking me. As I started to ease over to the side he hailed me on 13 (which I was monitoring) and said he was a coming up on me and would I please step aside. Told him I already was sliding to the right. You shouldn't have any problems w/ commercial traffic. Just keep you eyes open and use common sense.
(okay, some people have trouble w/ that last part!)
