Saw these nice looking Marsh Marigolds about 20 yards off the bank. They were surrounded by little trickles. Looked like seepage from the bank. There was grass growing anew and it looked like solid ground. There was a big bank that looked damp directly behind them and I could see a gravel road at the top of the bank.. I walked right up on the flowers and the next thing you know i sank to my waist in mud immediately. The ground seems like more water than mud BUT very cold mud..There must have been a huge spring on that big bank that welled up and seeped out through the ground. I grabbed a limb that was on the ground close to me or i would have been sucked up by the ground. It was scary. Took me 20 minutes to get out of the mud. I had to pull my legs out one at a time.It took me pulling with both my arms to dislodge my legs. Another hazard to put in the old memory bank
