Thanks for the responses...I was just wondering if I was being a big chicken. I think I am going to drive the road again and scope it out a little bit more closely. It's good advice to take some of the lane. The road is totally straight, so at least drivers could clearly see around me. Maybe I'll try it on a Sunday morning or late evening.
Just trying to add a little variety to my rides, and there aren't a ton of options right near my house....
