Coupla points to make.
1. Deal's Gap is an F'n Moron Magnet, especially at this time of year. It is wall to wall LEOs, it has an absurdly low speed limit, if the LEOs aren't there, it has a high density of Teenage Mutant Ninja Turtle outfit wearin', front wheel in the air, passin' on the blind curves, crossing into your lane, T-bonin' the innocents kinda riders. Like Yogi Bera says, "No one goes to Deal's Gap anymore. Its too crowded." Hey, if you don't believe me, take a look at page 86 of July's edition of Sport Rider.
2. I do haul bikes from time to time. Sometimes I can't face the 95F weather up the eastern seaboard on my way to northern New England, Quebec, and Atlantic Canada, so I'll haul a bike into central MA, or maybe even southern ME. If you're hauling a bike, the first order of business is to get a Cycle Cynch.

It was invented by an Aprillia rep who was tired of busting up the throttle on his wonderful Italian Stallions. Second, when I haul bikes, I prefer to either stick them in the bed of the pick up truck, or else use a covered trailer. If I use the bed of the truck, I mount a Condor Chock centrally at the front of the bed, and I load with a Big Boy II 10' folding ramp. It comes in two sections, each weighs only 40 pounds, and it folds up so that it fits easily next to the bike in the truck bed. The covered trailer I have is a modestly priced motorcycle trailer built by PACE. It has a drop down ramp type door at the rear, a side door for easy access, I have a Condor Chock mounted to get my tongue load right (checked with a spring scale on a crane). It has a very good suspension, and tie down D-rings strategically located. I use the bar harness at the front, and soft ties with regular clamp style tie downs at the rear. If the bike's got side cases, I might use that strategy after removing the bags, or I might just tie the rear wheel to the D-rings instead without removing the bags, depending on whim.
I like the trailer because of the extra storage space it gives me. I don't like the trailer because of the reduced gas mileage it gives me.
