DO NOT PADDLE THE UPPER CROSSWICKS!!!
We put in at Walnford Historical Park (Monmouth County). Our lower car was at the very nice Groveville Canoe Launch, but we never made it that far. There were so many very large trees fallen across the waterway--and so many tough carries up steep muddy banks through tangled, prickly weeds--that we pulled into Crosswicks Village, shell-shocked and exhausted, just before dark. It was at least a dozen carries--not to mention a lot of squeezes and scootches.
The kind people of Crosswicks, whom we found at a Boy Scouts meeting, were kind enough to give us--wet, smelly and exhausted--a ride back to our car.
Would higher water make a difference (in, say, June)? Based on the girth of the fallen, near old-growth trunks, and the number we squeezed under, I would guess not. But you go ahead and try.
