Aren't building projects FUN?!?! I keep telling myself that!
It will certainly be a nice home for that pair!!
One bit of advice. Make sure you build the site up high enough.
My Grandpa told me once to "get your site to grade..........then add another foot of fill."
I think too many times, people don't pay attention to this, and end up with issues that could have been avoided.
You may want to lurk around on.....
