Years ago we used to go down to the Ocean spray cranberry plant that faces the salt water, there is a smaller strip of grass that splits the plant with the water. We had a blast. You have to time it just right though, on high tide the dog can retrieve but on low tide you don't want your dog going into that muddy tide bank, my dog went for a retrieve and nearly sank. When we went there were hundreds maybe thousands of ducks. It was the funnest hunt I ever went on, the ducks were mud ducks and tasted like shiat but it was fun.
