I have been informed by Sherry, who runs the Rubidoux Nature Center
at the Santa Ana River Wildlife Area, that she has a number of good Eagle project
ideas, and would love to have Life Scouts work on their Eagle project at
her center. Sherry is the mom of an Eagle Scout herself, and very pro-Scout,
so please don't hesitate to visit her at the nature center or give her a call
at 683-4880. The nature center is located at 5370 Riverview Drive. MAP

Mary Burns at the Jurupa Mountain Cultural Center is also looking for eagle scouts to do projects.

This is more info for the guys looking for Eagle Projects.
The Louis Rubidoux Nature center (where Mike H. did his project) suffered heavy damage when the river changed course. 
At least one of the bridges mentioned was made as an Eagle project.
This place is near and dear us in the past they have always be great to us helping Cub Scouts with requirements,
helping Boy Scouts with various things they needed including learning about poisonous plants.
It's another resource for Scouts looking for Eagle Projects.
Sherry mentioned to Beth H. that she did have a wish list, so there may be other things needed as well.
