My wife and I arranged to get married on the stone beach at Tettagouche in 2001. We arrived Friday night after the Ranger Station was closed, so we deposited our payment in the box.
The next morning, we went to the station to upgrade our weekend pass to a year state parks pass. On telling the rangers we planned on getting married in the park, he replied "oh, you will need a special permit for that". I said "it's just me, her, and a court clerk coming up from Two Harbors...and we need two witnesses..."
"Oh, that's different. It's supposed to rain all weekend- but we'll stay after to be witnesses, and if it's raining we'll start a fire and you can get married in the lodge!"
Sure enough, it rained. Sick of sitting in our tent, we made the most of it-put on rain ponchos, hit the trails, and enjoyed the bridges and waterfalls. And that evening, the Rangers fired up a huge fire in the lodge stone fireplace, took pictures, and signed as witnesses for our wedding. One of them had been married in the park as well, at the river outlet to the lake.
According to Japanese tradition, if it rains on your wedding you will have a happy marriage. We've had a lot of adventures together!
