Now that's kinda kickin...
On the above design, I'd eliminate the state outline from the top, since it clashes with the main design and replace the text with "INGO" over the web address.
In the first design, I'd either change the type of guns pictured (an AR-47 and a SCAR aren't exactly run-of-the-mill stuff that Hoosiers own) or eliminate them entirely, and move the state outline to the right side of the text; otherwise it kinda reads like "JINGO" or "JINGunowners.com".
These are 2-color back, 1 color front.

yeah- having actual guns on the shirts may be abrasive to the sheep's gentle psyches.
