Loveland pass has an elevation of 11,991 feet above Sea Level.
Denver, Colorado, about 60 miles away, is about 5600 feet above Sea Level.
That's an average grade of 2% for 60 miles, although the road at its steepest point is about a 15% grade.
So, no matter how you slice it, no matter how badly you're fleeing from a drug-deal-gone-bad, making it to Loveland pass in under half an hour is quite the accomplishment.
Happy 68th birthday, sorry it's a few days late...
