Yes the creeks were dangerous. Since I lived on the other side of the river most of my exploration was done on the Frampton Marsh side. The several deaths reminded me of an incident. During the summer holidays around 1949 a group of us went from Boston Skirbeck Quarter area to Frampton Marsh every day on our bikes when the weather was fit. There had been a person lost, whether he was a fisherman or what I can't remember now, but he had been lost for around a week. One day in particular my friends called for me but I couldn't go as I was booked in to the dentist later, but I was allowed to go the following day, and they said they would call for me. Next day came, but they didn't, and we wondered why. I was about to call on one of them when he appeared at our back door to say there would be no more trips to the marsh for the foreseeable future; the previous day one of them whilst crossing a water filled creek had trodden on something soft. The body (for that is what it was) rose up out of the muddy water and floated on the surface, scaring them all stiff. No further trips to the marsh that year! Army pillbox side of railway off London Road instead.
