OK ladies and gentlemen for one you should always be concerned if the EPA gets involved in any matter. I work for the State of Nevada Bureau of Air Pollution Control. We work with the Clean Air Act daily and are in constant contact with EPA.
Like Al said by supporting SEMA and NHRA you are doing a lot if you add a call to your local Senator and Governor you will help the cause even more.

Do what you can to get your voice heard! We all love the sport of drag racing and modifying cars, if you want to keep your freedoms call, vote, and most of all pay attention. Taking action on these kind of matters help win lawsuits against the EPA and believe me we need a lot more wins.
