I'd wear a campaign hat, but I'm too thrifty (read, cheap) to purchase one.
I hear ya. I lucked out with mine First one I earned upon completing Brownsea 22, as that was the recognition as well as a patch. The council issued US GI surplus hats to those that graduated. That one went through 1 hurricane, numerous camp outs, being shot at by German Scouts, etc. I did buy a BSA chinstrap, but use a British Scout Association's hatband that is branded with the camps I worked at over there, and a plume I got at BP House.
Second one issued to the "youth" staff who worked JLTC. It was number of years after my BA22 course that the council did JLTC. At 20, I was a "youth" and SPL. I was also the only person to have done BA22 or JLTC on staff. Council reintroduced the Smokeys upon completing JLTC, and since none of the youth staff had Smokeys already, and mine was "experienced" They issued us ones to wear. Again US GI surplus hat with Scout Association branded hatband and BSA chin strap. However, I gave my BP House plume away, and now wear a 2007 Century Anniversary plume.
