Good thread!
There are plenty of folks WAY too old to be AK Rowdies who also feel very indebted to Caleb Porter. We are not on campus as you are. But most of us would support whatever you decide to do. Ian, AJ, et al, I agree that this should be initiated by the AK Rowdies.
Please forgive my maudlin sentimentality, but I once again suggest singing "You'll Never Walk Alone" ala Liverpool FC. (Has anyone seen the series on FOXSOC?) The song is short, classy, and traditional. Better yet, get some choral group from the university to do it.
I promise not to mention it again, if you just think about it. Balloons are pretty FF from good enough, if you ask me.
