Mhm. More and more people are learning about it, but wrongly.
One of my family members saw two guys doing Parkour at some of my regular training spots at UCF, and inquired about what they were doing. They said "We're doing Parker". Pronounced just like that. Thankfully, said family corrected them and went on her way.
If they don't even know how to pronounce it, I'm doubtful they know how to safely do Parkour, or explain it well to a stranger.
I have that shirt, but in a sweater
