I posted a while back about safety concerns at Saguaro National Park East and a ride the park was organizing.

Here is the pertinent info:

Paul Austin, the Rincon Mountain district ranger is also working with GABA and Bike Ambassadors to organize a ride though the park on April 10, 2010.

The Saguaro National Park East is sponsoring two rides through the park on Saturday, April 10.  The first ride starts at 8:00 AM followed by a ride at 9:30 AM.  The rides on the Cactus Trail road are intended for those who have never ridden the route or have not done the loop in many years.  The rides are supported by the Park Rangers, GABA and the Bike Ambassadors. Safe riding techniques will be emphasized and support provided to those who may find the climb on the back side a little more difficult than expected.   So please come out and enjoy a ride through our magnificent National Treasure. Please remember to bring your pass or be prepared to pay applicable entrance fees.

I received word from Austin that the fee has been waived for people participating in the organized ride.
