While I'm in nostalgia mode and in honor of the day, here's a picture from St. Patrick's Day, mid-70's. I was doing my undergrad work at a small, private, catholic liberal arts college in Montana, and St. Pat's Day was a big deal.
This shot was taken at the traditional (although don't know if they still have it) St Pat's kegger out at Canyon Ferry near Helena. I recall it as a clear, brisk day with snow still on the ground. As you can see, I was holding an Oly cup, but you'll have to trust me when I say that I acted with the utmost decorum.
