Out here in Kansas, we also know the pleasures of popped milo. (For those who don't know what milo is, it's a type of grain sorghum that's grown for cattle feed. Much better adapted to the Plains -- and thus, much more sustainable -- than pesticide-intensive, water-guzzling corn.) Milo has much smaller kernels, so it's harder to pop a full bowlful of the stuff, but it's quite tasty!
I've never had it any other way besides just a milo-harvesting-season snack, but I just found out you can actually buy the stuff!

We have fooled around with growing heirloom popping sorghum for a couple years. Fun stuff.
Beyond the pleasure of eating nutty miniature popcorn kernels, I've found that country mice love to stuff every kernel they can fit into hollow broom handles and PVC pipes--by the looks of things I must've fed an army of mice with my crop. And it's murder on the fingers if you ever get cute and try to string it onto your Christmas tree.
