The other woman and her husband were in their seventies.
But here's the real story: My friend and her husband were attending a WPA event called Do It.
Now, WPA stands for Western Pyrotechnic Association. And, Do It is an event held in Nevada and is short for Do-It by the Ammo Depot.
Of the Do It event, the WPA website says:
. . . this event came from the need to have a second event during the year and geared more towards the hobbyist. . . .and now boasts attendance in the triple digits. This event is geared towards those who like to develop and create pyrotechnic items.By my tally, we have over a hundred amateur pyrotechnics in RVs in the desert by an ammo depot.
I would sooo not be worried about the mat.
