Commemorate the 25th anniversary of the McDowell Sonoran Conservancy.
A celebration in its honor will be at 7 p.m. Friday, Nov. 4, at WestWorld, 16601 N. Pima Road.
The nonprofit organization champions for the sustainability of the McDowell Sonoran Preserve for the benefit of this and future generations. The preserve features 170 miles of scenic trails that can be accessed from 11 convenient trailheads. The preserve opens at sunrise and closes at sunset to provide desert wildlife -- which is more active at night -- a break from humans.
