 It really is a pleasant beach. There's ample shade, a few picnic tables, and plenty of room to spread out. But this beach isn't always accessible. Periodically, it's closed due to higher than acceptable levels of E. coli in the water. E. coli is a bacteria that can be found in any natural body of water. If ingested, it can cause stomach cramps, diarrhea, vomiting, and even fever.
