Well, it's hard to argue against doing both. With multiple growing seasons in Florida, and generally nice-weather to bike in, both have become year-round habits that I'm learning to do better each year. Yes, I already know how to plants seeds and ride a bike, but learning involves mastering your area considering crop rotation, starting seedlings indoors, composting, and finding the best, safest and most efficient bike routes possible. None of it comes without some effort, but both yield great rewards.
