Two things........the Exeter is in a closed (inland) zone and the location you emblazoned for all to know and find out about, is also in the inland zone but it is not the Exeter River.
Everyone..........do yourself a favor (and all the others who have hunted spots over the years), please do not provide location specific details on an open forum. I know we all try to help others etc.....do it through pm's when possible. When details go on an open forum ANYONE can read the data, not just your fellow members and cyber-friends.
So Tom........the next time you run up the river to the treatment plant, you'll probably find someone in your spot!!!!! I can guarnatee you this....I was there well over a decade ago and don't need your advertising, please! Also, for your own good, check your regulations regarding the NH zones carefully. The coastal zone is all that remains open.
Welcome to the site....just be careful and also considerate.
