My hometown was on a MoP branch.  As a little kid I remember seeing Geep 7s and later GP15-1s in the iconic blue trundling through town, and even had the chance to ride with them as they switched Hudson Cream Flour.  I've been a fan of the MoP since that day, and adopted the other roads in the family (T&P, KO&G/MV/OCA&A, C&EI) as well.
