Local mexican grocery store used to carry them but don't anymore and local ranchers selling their beef direct to the public have no idea what they are. Will be checking with local butchers to see what can be done there.
In the meantime, any recommendations for a good source to have them shipped? Have found several online, but their pricing is ridiculous ($20++/lb plus shipping). Of course, beggars can't be choosers. Just hard to stomach when I know if I had an HEB nearby I could get them for <$5/lb.
And Merry Christmas to everyone!
