Oregonrain - glad you are on your way to beautiful Lake Winnipesaukee. We are all rooting for you.
Not all of us are at the Lake, but mentally we all are.... I currently live & work in Chicago, far from NH! But will get back as soon as I can. Grew up going to NH every weekend - any time you get there will be wonderful and full of good memories.
BTW - re: Fireflies. In Chicago suburbs, I have had fireflies every night for the last week. They usually show up here around July 4th fireworks - they are early this year. Not sure when they arrive at Winnipesaukee, maybe a couple weeks later?
Good luck, look for moose very early 6:00 AM-ish, and fireflies mid-dusk - maybe 8:45-9:30 PM.... ENJOY
