I'm not a native Floridian, but my wife and son are. We spent the weekend connecting with nature at Wekiwa Springs State Park -- a beautiful spot for a Mommy & Me session. It was overcast, so not too hot, and we were able to enjoy the trails, the wildlife and the water.
It's a great place to explore, either by foot or in a canoe or kayak. And it's clearly a great place for an impromptu photo shoot.
