It rains a lot here in central FL too. It's been raining non-stop since yesterday afternoon, storming too. (But temps are in the high 70s to low 80s.)
When it's warm and raining, and not lightning, the most fun thing is to go outside and play in the water puddles and mud. Mud fights are fun and messy. Then, if the rain isn't falling enough to clean off our mud I'll pull out the water hose!
Cold rainy days are good for catching up on the boring housework. Cold stormy days are my excuse for doing nothing but the minimal and reading a book. :)
