Dang Peter, even your memory stayed there....must have been one heck of trip bro! 
Bob,
LOL. I don't remember buying it so it must have been a gift. I am not a big drinker of hard liquor so I must have put the Dobel in my liquor cabinet, where it sat with the rest of my hard liquor. It wasn't until I ran out of the tequila that I brought back from my last trip to Mexico that I checked out my liquor cabinet to see if, by any chance, there was another bottle of tequila somewhere in there. There was--a Jose Cuervo--that I had purchased on another Mexico trip. And next to it was the Dobel.
