About Indian Rocks Bridge

We have a HUGE responsibility to protect our children and their futures. Our Gulf of Mexico has nearly been destroyed by the Deep-water Horizon catastrophe and many families here will never recover. Paradise lost, so it goes. I’m doing my best to apolitically educate anyone that cares about the impact on our environment by technology and “for-profit” progress. We forget, too frequently that we SHARE this planet with millions of other life-forms and as the most “powerful” species, we must be more cognizant of our greed versus the well-being of our planet. Thanks again for visiting and please check back often. -Gregg indianrocksbridge@yahoo.com
