If you haven't ordered bees already, get going! Package bees from online suppliers are selling out quickly, but you can still get some. I've compiled a list of suppliers who sell and ship bees online, and most of them still have package bees and queens available for this season.
Check out the other supplies you'll need for beekeeping as well. If you're interested in top-bar hives, I just got a great newsletter from the CUESA featuring an interview with an "anarchist" beekeeper who's passionate about top-bar beekeeping, and articulate about the reasons why. And, if you decide that top bar is right for you, Gold Star Honeybees sells top-bar hives (and package bees for pickup in Maine).
