I got mine on eBay. Around eleven bucks. Several sellers have them.
At first I was going to get one of those “Plague Doctor” masks, but decided that would be very uncomfortable... Then I looked for one with sheep, but thought that may be too subtle for the sheep in the store. Ran across this one, and immediately ordered.
I really don’t want to spend $15-$20 bucks for a useless piece of cloth that will be contaminated beyond even uselessness after the first 20 minutes I wear it but a good FU message like that makes it tempting. :)
I made a couple of homemade masks from the legs of an old pair of jersey-type sweat pants. Too hot to wear in May much less now in July.
My cowboy bandana gets me in and out of the grocery store and Post Office every two weeks or so and if necessary I am stocked up to stay at home for several months. I refuse to participate in society as much as possible until this madness burns itself out. Starving the corps any way I can.
