A suggestion re: SN's participation.....
I was an SAE. Back in my era ('70's), SAE was very strong - including in Buggy.
Times changed, and The House had no lack of problems for many years: slackers, low number of members, finances, problems with CMU admin, etc., this included not participating in Buggy for several years. It was touch and go, for a while.
SAE is now back in gear, and the situation was largely rectified by the alumni getting tough on the 'bad brothers' and stepping in and helping straighten out their various problems( finances, probation, etc.).
I'd hate to see SN not participate. I think historically SN has been a good competitor, especially as far as free rolls go.
In SAE's case, it took the concerned effort of long term devoted alumni (mostly locals to Pgh) to get things back on a straight path.
