We once gave patches (think stripes on a military uniform) as well as award pins. Haven't done either in years except for the 2 or 3 who actually kept up with them. Won't do it any more since we had a name change and we aren't going to order any more pins.
Since we are opening a new facility in about a month that doubles the size of our campus, our "volunteer event for the spring" was a reception and early bird tour. We didn't have any awards as a banquet would, and I haven't heard a single person ask about award winners, etc. So that might not reappear either next year.
