went out smelting in exeter NH once very scary this was a brackish tidal river and if you do not get off the ice in time there is a 15+ foot gap between shore and the ice due to the rising and falling tides. I would like to do it again but i moved 500 miles away and there are many better fishing options here so i doubt i will be going back anytime soon ... unless of course NH has ice before us I may have to go back and visit...
