If you are into Pilsner at all you need to try out Golden Shower. Not as good as the 90 but tasty for a Pilsner. If you are pulling a Madden and going out for 12-15 stick with Lite beer from Miller.
You have to at least find your cute little employee at your local Total Wine and ask her if she is familiar with Golden Shower and if she can help you out with your search.
Believe it or not the local Dogfish Head pub does NOT carry 90 Minute.
