I live on Grand, on the south end, mouth of duck creek. Absolutely love it!! Mosquitoes were worse at my house in Owasso then here. But, I, along with all my neighbors have Martin houses so I'm sure they keep the mosquito population down. Spiders are horrible! Anything around water and the spiders are going to be bad. You can spray for them though which helps quite a bit. There is also a system called Spider Be Gone which those that I've talked to that have them say it works great. It's expensive though, cost around $5K to install for average size house. Snakes are not bad at all, I've seen 4 black snakes in my yard over the past 11 years, that's it.
Can't help you on the realtors, do not know of any of them that are any good around the lake. When we were looking at property 13 years ago the agents only wanted to show you their listings, it was very frustrating. Best way to look for lake front property is by boat, it will take you forever by car. Can't help on the karate or the band questions.
Regarding positives/negatives. Lack of restaurants sucks, lack of shopping sucks. But the positives far outweigh any negatives. You get to wake up to this every morning!
