I'm a fan of funny Florida crime fiction - an odd genre. Read Carl Hiassen or Tim Dorsey (among others) and you'll see references to Florida the way it used to be before rampant overdevelopment and destruction of natural and historical resources.
I took a ride this past weekend to Cedar Key. It's far from unspoiled, but there are quite a few remnants of the old days; wooden and tabby buildings, stretches of coast with nothing on them, a few signs for businesses around for over 100 years. No chain anything (I had to forego points

); small independent restaurants and motels, small food markets, no 200 foot high gas station signs.
I'm looking for other suggestions of concentrated Floridiana, preferably in the north 1/3 of the state. I've done St Augustine. I'd like to find a couple more treasures to explore along the Panhandle this winter.
