Like Phantom Catcher, Kennywood's my homepark, so I'm certainly biased. But!
I honestly don't know how anyone could possibly skip Kennywood if they're in the Pittsburgh area and have some free time. Of all the parks I've been to, which isn't some ungodly number, sure, it's either my favorite or one of the favorites. The food, the atmosphere, the coasters both classic and new-age, the great old flat rides, the scenery and gardens... The list goes on and on.
It's eight miles from the Golden Triangle, so there's no reason not to hit it. ;)
