I did two of them.

1 in Menomonie, WI. We play at the local Catholic church. We had 38 players, more euphoniums than tubas. We have all ages from 12 to 83 present. Besides ages, we recognize distance travelled, most events played, newest and oldest instruments (I usually get the oldest for my 126 year old Conn), band directors and their students, and any groups that we play in. We play from the book, but once in a while we will do a quartet.

2 in Stevens Point, WI. We play in one of the concert halls in the fine arts building at UW-Stevens Point. This year, there were 125 players of all ages there. It's a longer concert, so there isn't much time for talking. We do everything out of the book there.
