It's a free country. Let them try to sell them....No problem.
But I would remind folks that ski/snowboarding takes place at public places with a wide range of ages from kids to adults. Not that I am a prude or anything. But it is not like we are going boarding at a bar that is 21 and over. Or even 16 and over. There are pretty young kids around...
And while I am complaining...I have not learned any new words boarding (i am 44). But It is kind of crappy when kids are f' this and f' that in front of like 8 and 10 year old kids.
