My hubby and I really want to get into camping. But real camping like in a tent out in the woods. I'm not sure what kind of gear we REALLY need and our budget is tight for it so I was wondering if any of you have any suggestions or ideas for what kind of gear we really need. We have a 10 year old girl, a 3 year old boy, and a 19 month girl. We already have a tent and sleeping bags but I was wondering about getting an air mattress.
