Just a word about vegans and vegetarians - very often they don't eat meat because of moral or ideological reasons, not because they don't like the taste!
We used to do it all the time when I was a kid. Someone would throw a party at a gravel pit. We'd take our dates and someone would build a bon fire. We'd roast the watermelons over the fire. When they exploded, everyone would jump up and go out in the bushes and get a piece. Fark it was good.
