You are right. We did check it out with a rabbi beforehand. We wanted the wedding to be inexpensive, but definitely kosher.
We are blessed to live in an area with lots of kettle-hole ponds which were formed when the glaciers receded 10-20,000 years ago, long before man was in the business of pond-making.
Our wedding ceremony was on a ridge above one of these ponds that we walk around frequently.
The pond that my bride-to-be went to also had ample, inexpensive parking, another big plus.
It was Walden Pond, where Henry David Thoreau spent his time philosophizing on self-reliance, survival, independence and the natural world.
We’ve had a lot of rain this summer, and the pond was filled beyond its usual banks. The usual “beaches” were closed, so she did have some trouble finding a spot where she could get in or out. She came close and found a spot where she could get in easily, but couldn’t get out, which made for some humorous photographs of her trying to climb up on the rocks, with the help of her friends.
