Thank you all ...
... for your responses. Thought you all might be interested, I also got an email from Commander Steven Stilleke of the US Coast Guard Search & Rescue @ Washington DC that directed me to the Boats US article that states:"To date, flares can not be recycled but special care should be taken with their disposal. Throwing flares in your household trash can cause a dangerous situation and setting off old flares can result in false distress reports. To dispose of expired flares contact your local county public works department, police or fire department. Alternatively check with a local boating education group. They often use old flares for educational purposes."Again, thank you for the info re disposal and how to better use this site...Jeffrey
