If root beer, then why not Root Beer Schnapps? Used to pick up a bottle of the stuff at the Lake Aire Bottle Shop on London Road, just past the junction of US 61 and I-35. Think the distiller or company was Phillips. Couple of oz of the schnapps and top off the glass with A&W Root Beer and kick back. I do still have the old school heavy glass mugs, at one point you could actually buy them from the outlet.
