Although I am a daily bicycle commuter, I have not really done a overnight tour (except for a short overnighter to a local park via a bike path years ago). I am planning an overnighter with my 16 year old son to a campground at a nearby wildlife center (about 50 miles one-way). Yesterday afternoon we did a quick recon-style trip (by car) to the campground and to check out the route. I have had some gppd advice on the route, and it seems so avoid large suburban roads to get out of town, then the main route out into the countryside does not seem to have much truck traffic.
My concern is mostly with riding on these rural 55mph roads with my son. We have ridden extensively in-town, but for the most part avoid ridding with traffic over 35mph by using side roads and neighborhood streets. But at least 22 miles of the trip will be on a US route with posted speeds of 45 to 55 mph. The roads are well maintained, but have little to no margin to the side.
I know that this is probably parental concern about the safety of my son, but I feel I need to discuss this with an experienced group. How do you deal with riding for miles on two lane roads with high speed traffic? How do you mentally deal with the real or imagined 'threat' to you or your loved ones safety on these types of roads?
I appreciate any insight you can give.
