I've used the Jon boat trick many times myself. I like to kneel on the rear bench seat, hang one leg over the back, and kick my way out. If you're wearing cleats, and the surface is swept clear of snow, you can really get up some speed.

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
