Here's an interactive
map. But before you visit it, consider these pointers from Lookout Mama:
The interactive (Mapquest) maps are kind of old.
Desert Sky is also accessible from the north by the Loop 101 Freeway.
Take it to the Thomas Road exit and go east to 83rd and make a right (north) to
the site.
Right now there is MAJOR construction going on on most all the area
Freeways. During the weekends several of them are closed in sections from
9pm Friday until 5am Monday - usually including the I10 on the west side of
town, which is the main access to Desert Sky.
So you might want to make allowances for local traffic and leave
earlier than anticipated.
You may want to check
ADOT
(Arizona Dept of Transportation) for up to the minute info.
