Iowa has issued new license plates this year; mine expire this month and I'm thinking about getting my new plates personalized. I'm not really a personalized plate kind of guy but when I casually mentioned it to my wife, who I fully expected would shoot it down, she surprisingly had no problem with it (as long as it's not offensive). I have searched the DOT's website that immediately tells you if something's available. You're limited to seven spaces.
I tried all the obvious ones (BUCKEYE, GOBUCKS, OHIOST8, OHIOWA, OHIOWAN, etc.) and had to get creative. Here are 16 that I found are available.
