masiman, that train you are pulling in your picture is incredible. Hopefullt you oldest daughter gives you some help pulling it.
I never thought of hitching our trailer to the trailercycle. I will have to try yhis when my wife can't make it on a ride, because I can still get the 2 youngest in the trailer and keep it under the 100 lb wight limit . I am sure the kids will like the change of routine.
