My back in Lynn

Met George and Jambalaya at the ball field lot early Saturday to visit Lynn woods and some old school trails, and a few new ones, for a mini-epic tour of George's manicured stash. I had built my dually back for the occasion remembering the beating I got here with my hard tail.. With the aggressive rock and boulder strewn lines of Lynn you're better off with as much travel as you can bring...unless of course you're a super skilled trials rider..
Cold and super windy, I had a large backpack with extra clothes and lots of food for myself and Gus. Knowing George's style of packing everything one could possibly need I didn't want to forget anything, so my pack was pretty heavy, as was George's.
We started out on the Hike, a few changes have been made to the trail since the old school days of DM, KD,JH,GA,MD,BB,AG,AP and others. My gears were totally sucking my will to try anything that required stomping force. I had mistakenly installed a used cassette and a new chain, George quickly nicknamed me "skip". Otherwise I was enjoying the cheat factor of six inches of travel front and rear.
We banged and smashed our way over to Balanced Boulder and I needed to stretch my back...but it didn't help. Call me a nancy boy (thanks for that one Barry) but I couldn't handle 4 hours in Lynn with out getting beat down. Yeah, I can cross Costa Rica on a single speed but I couldn't pedal 10 miles in four hours (in four hours...you do the math) with out sheer agony.
I think because I haven't done a single sit up or stretched my back or legs in two solid weeks, but now feel like some has inserted thumb tacks in my lower back.
Might have to see a professional for repair. Four hot baths and lots of vitamin I, nor beer therapy have helped.
Thanks for the ride G. Gus really enjoyed himself.
