Eagle Rare or pretty much anything from Buffalo Trace can be hard to find at retail in Dallas. The bourbon seen is a bit much here. There are literally guys who DAILY wait outside the big box liquor stores (Total Wine, Specs, Goody Goody) at open to see if the store got anything allocated. Never could figure out how they can do this and maintain a job.
Then you head on over to a state like California, where the local palate is more into clear spirits, and you can find Eagle Rare pretty much anywhere, including the grocery stores thanks to their relaxed liquor laws. The unicorns are still heavily sought after, but demand for the regular stuff is normal.
