Inspiring Connections Outdoors (ICO) Parks4Kids Program

San Diego ICO is an all-volunteer program of the Sierra Club dedicated to providing outdoor experiences to low-income youth who would not otherwise have the opportunity to actively engage in nature. San Diego ICO has created a fundraising page in the Parks4Kids Program, which is sponsored by The Outdoor Foundation. It operates a bit like a GoFundMe page (but Parks4Kids does not take any of the amount donated). San Diego is seeking $7,500 to provide funding for 30 hiking and 5 camping trips during June 2016 – May 2017. Make a tax-deductible donation HERE.

Resist, Recruit, Train, and Sustain

Over the past ten days, we’ve had to accept a tough reality. But although it’s definitely going to happen, a Trump administration will never seem normal, nor should it. We already know that the corrupt, cynical, and racist values that he and his inner circle bring to the White House will challenge everything we stand for.

As we move forward with a new Congress and this new administration, here are some early thoughts on how the Sierra Club will confront the reality of President-elect Trump.  Read more here.
