Just Google "Dutch Oven Cooking" and you will get endless sites and ideas.
Yes get the "camp oven" it has the legs. Wifey gave me a "Cast-Iron Cooking for Dummies" book. It has lots of tips on the care and use of all types of cast iron cook wear. I started a notebook just by scanning the net for good recipe's and printing them off.
Once you get started, you wont just own a "dutch oven". You'll want to scout the yard sales, flea markets, auctions, ect for all sorts of cast iron cook ware.
One of my favorite deserts is fresh apples off of the neighbors apple tree turned into a apple crisp!
Get your feet wet and start cooking!
