We rented a boat and thought the boat, marina and surroundings were great. This is a really BIG lake and the water is great. We tried fishing for a few hours and just got a couple bites so can't vouch for that but swimming was a lot of fun. There is NO food to be bought on the weekdays so plan accordingly and pack your own lunch.
The downside - and this is a big downside - is the people who "work" at the marina. They are downright frightening in their mannerisms and actions - truly it's like dealing with zombies as they shuffle slowly about and mumble things. And it wasn't just one of them either - it was every single person. It got so we didn't want to deal with anyone and felt a sense of relief as we left unharmed. Due to this reason alone - we won't go back as it's too creepy.
