Quicksand Fans

Does anybody know of any good spots in NYS, mainly south eastern part that has quicksand, or maybe mud bogs?
I only know two small spots in the wooded areas of New Windsor ny.
I was hoping there would be something in Harriman or bearmountain.

I remember my first time mudding, I was hiking in a nearby woods in Newburgh ny and I came across a black slimy mud pit, so I undressed and stepped in and started sinking, I thought this is cool, I got really
excited and turned on, I sank up to my neck. The slimy mud against bare skin is amazing. Every time I go hiking a search for that one mudpit. I hope to post some pics this summer.
