Maintaining an exhibit at the National Museum of Industrial History (a Smithsonian Affiliate) requires an annual financial obligation of $10,000. That alone keeps the exhibit in place, but it doesn't provide for any updates and improvements. The Propane Education and Research Council (PERC) has generously taken on the ongoing, annual, payments, which is a tremendous help. However, it's been over two years since the exhibit opened and it's time to make some modest improvements, and we need YOUR help to do that. It took over two decades and hundreds of volunteers and financial supporters to get us to this point, to the tune of about $400,000! Please pitch-in whatever you can. Future generations should know our story.
