Thanks for the welcome, 'Ara' (can I call you that?)...yes, I'm a true 'Old School' Alum. I almost chose "Fieldhouse" for my login name, in memory of the "intimate" and truly enervating shoulder-to-shoulder pep rallies there. I'm also a veteran of Emil T. Hofman's Chem lectures/exams...if you are of a similar "vintage"...would enjoy sharing a few recollections.
