I knew I had posted something a while ago (Feb 07) about carrying all those tools for tire and bearing repair as a guaranty they would not be needed. Well, the guaranty is now void. The right aft tire blew out or just went flat. I am unsure what happened as I did not notice any difference in the tow. A good samaritan passed and made frantic circular hand motions. Since I am pop culture illiterate, I thought this might be a new gesture indicating his displeasure with my driving and his certainty my mind, like a tetherball game, was wrapping itself around an imaginary pole! Anyway, I could feel nothing from the trailer to indicate the rim was about to eject the shredded remains of the tire like a flavorless wad of tobacco. I am duly impressed with the tandem setup; could have continued on three wheels for many miles. The tire change went well due to all the tools, supplies (including the hand cleaner) and support from my wife who vocalized encouragement from the cab:"Turn the engine back on so the a/c runs". Yes, machinery heaven and domestic bliss!
