I have a friend that probably lives near you, he's on Ansley Path near the mail stop. He usually has a kayak on the roof of his Nissan Pathfinder. One morning at MVP he told me he had gone kayaking, I asked him where could he had gone that quick and be at the gym that soon. He said he goes to Lake Okahumpka Park.
If you take Buena Vista south to the end at Hwy 44, turn left like you're going to Leesburg, but the state park will be about a 1/4 on your right. If you reach Morse red light, you've gone too far. Here's the address if you want to put it in your GPS, 6085 FL 44, Wildwood, FL 34785. I've driven by the place but I have not been there. It shows there are a lot things for being so close. Here's a photo of the boat launch and a link to their website
