The one in NM looks interesting. There is another spot closer to home I keep looking at while walking the dog. It’s a spot a lot of kayaks pull into and I’m guessing a few have dumped gear overboard. It would be a mile walk or just float down the river with my dingy loaded with gear, dive and then float to the next entry point and have the wife pick me up. That would be in the spring when the air has warmed up!
