Yeah, New Mexico's is great. It's simple, looks good, and captures the spirit of the state.
I'll say this - As a native son of New Mexico, I hate me some New Mexico... but the Zia is hella easy and fun to draw when you're like 7 (and as symbols go, it ain't half bad). I was actually kind of horrified when I discovered what crude pieces of shit every other state flag was... I mean, ours looks like something you'd carve on a tree but everyone else's looked like a committee of 11th graders worked clear through their pizza party. Colorado was bad and Texas was worse but once we started doing reports on other states in like 4th or 5th grade the true horrorshow kind of put us all off.
