Sadly since derry is on the westside of meadowvale area, it leaves options for the people of the area to either attend the highschools of Meadowvale SS, West (free) Credit(s), or Our Lady of Mount Carmel, which are all dog shit schools ran by wannabe kids who act hard, sell drugs, and finess and kawal yutes. Derry is filled with snowbunnies and dirty hoes, most people hangout in the summer by lisgar ball court and 7/11, cop puffs from danton or derry convenience, hang out at Union, and often youll find mount carmel kids by Timmies after school hours. Late at night you can find crackheads hanging by the Rabba or by Scotiabank in the areas, usually cracked out, or making too much noise.
