You're in for the ride of your life, Phillip. Enjoy it! I think the most fun in gardening and homesteading is when you first start out learning the ropes, very exciting.
I'm not a big proponent of the "3 sisters", although if you plan on growing a dent corn or field corn you may have good fortune with it; modern day sweet corn doesn't seem to hold up the beans well and once the stalks lodge you have a mess on your hands. And psst, those goats will know a day ahead of you when to go harvest your corn! Beware! :>)
I'd also recommend you go help (and learn from) those ladies who man (or "woman") the canning kitchen. It's actually fairly fun and a piece of knowledge you should have hands-on skill with, enough so you can pass the knowledge on to others. Our country needs whatever blessing or knowledge you can offer it.
Hope you will be posting your goings-on. Looking forward to watching your growth.
