Casey, I like the last one, the gas mask...that should do the trick.
Seriously tho, wind does kick up sometimes, if you think you need protection the el cheapo ones you find in the stores should be ok. I'm just coming off 1 1/2 yrs of oxygen therapy after a punctured lung and have severe COPD...on inhalers too. Sometimes I find a bandana helpful, but don't feel the need for respirators.
Do bring shorts, and a jacket too. Can get rather chilly at times. Even a knit hat feels good in the evenings around the campfire.
