We went on our beach picnic I had a blast with the seagrass. Tons of crabs live in it, and as you walk through, they scurry about. Seagrass is better than regular tall grass - no mosquitos.
The only beach problem I had was on the secluded part of AC that didn't have resorts, there was a lot of trash washed up. But to me the seagrass is no problem.
