Sounds like fun Mark. Iv'e been trying to do a family reunion for years but it never seems to work for everyone. The whip cream is a better Idea for sure shaving cream is to slippery and tastes bad.
This will be our second reunion. Should have started doing it years ago. My son's is a perfect place as he has lots of room and a large camper to sleep the excess and a large pool as well. We had a great time last year.
