For what it's worth, I grew up in NJ and currently live not too far from where Washington actually crossed the Delaware River. So common that the locals rarely go watch the river crossing reenactment every year. So, it was about 10 years ago I actually went to watch to see what all the hubbub was all about. The previous days had a lot of rain, the river was running high. The time came for the big launch/reenactment push off. The current was too strong, the actors doing the paddling gave up. Washington didn't cross that year but faded into the distance going backwards down the Delaware. I recall nearly everyone watching said that's not how history told the story.
The other big joke for this area of NJ is that there are signs up everywhere stating that Washington slept here.
