Here's alternate directions:
I-25 to the 1st street exit (9
Head west a take a left onto Union Street
(I believe this is the 2nd street that intersects. The first, with a light, is Main. Union St. doesn't have a light.)
Follow Union until you cross the river.
(NOTE: if you need any gear you'll find The Edge on your right in the first? buildings on that side of the road... there's a restuarant next to it and parking there)
After you cross the river, take your first right. This is Corona Street
It follows the bottom of the course for a bit.
Stay right at the fork just before the park
At the end of the park, there's an intersection. Go straight (dirt road) to the parking lot
