Spoiler: Pictured: the average state flag
Texas, Arizona, and New Mexico all have great designs. California, not so much.
Also, while Alabama's flag is incredibly boring (and also the description is ridiculous, since there's a saltire that is exactly what our flag is, but our flag is officially a different saltire with the colors changed. Because Alabama is ****ing stupid), there once was a very similar flag (that our current one is derived from) flown over Alabama during Spanish rule which was much better designed. The Cross of Burgundy.
Spoiler: I maintain Alabama should change its flag back to this
