This is a serious question, not a troll. I can see how it might come off as an obvious yes or an even more obvious "no way are you retarded?"
But I simply don't know.
Can I just get a fat stick of chalk like what kids use to draw on the concrete, keep it in my pocket, and rub it on my hands before I lift? Or crush it up to powder and put it in a bag and bring? Mainly because it'd be easier and quicker to acquire than real WL chalk.
Please don't yell at me if this is a really stupid idea... I have no idea whether or not WL chalk and kids chalk is any different. In my mind, they are the same.
