All par 3's unless the course has legitimate par 4's and 5's.
A lot of courses around here have stupid pars, like Wingfoot State Park. There's not a hole on that course that's a true par 4. Deis Hill on the other hand has true par 4's from the longer tee's.
Yeah, Blendon Woods Metro Park has the worst pars I'd ever seen.
DGCR failed me on that one, It rated like a 3.5 when I hit it up. :\
