I will be retiring soon and am looking forward to starting serious bike touring. During a recent road trip (by car, unfortunately) through the southwestern U.S., I couldn't help but notice the rumble strips that now plague the shoulders of most main highways. In some places they take up the entire shoulder. I had almost settled on getting a 2 wheel trailer, but am now seriously reconsidering that as it would be hard to keep one wheel out of the damn rumble strip. How are you folks that are touring with 2 wheel trailers or trikes handling this? You can't take the lane for long on many of these roads due to high speed traffic. Thanks for your comments.
