I forgot to add that this will be returning to my roots so to speak.
About fourty years ago my Mom & Dad rented a house on Winnisquam. One day my Dad rented me a little tin boat with a small tiller for a day. That was one the best best memories of a vacation as a kid I ever had. Been wanting to own a boat ever since.
I'm not sure what you are thinking of as the new ramp but the state ramp in downtown Laconia on the river by the water treatment plant is pretty much brand new. It's free and in great condition. It's possible that if there is a tourny or heavy weekend traffic that this ramp may fill up (I don't think there is overflow parking). I'm going to guess there is parking for 20-30 trailers there.
Was on Winnasquam today with the family and used the new launch. 2nd time I've used it, this time was during the week and it was great. The first time was last year on a saturday and it was real busy. Like someone said earlier go through town and you can see it, I believe the name of the road is Bay Road or Bay street.
