I just started a campaign based on US people from 21 to 45 in USA and started the campaign just now. I have the tshirt made on Teespring. Someone thought to try this kind of thing on current events. I keep hearing about the ice and snow storms nearly all over USA, mainly on East Coast where the bulk of the population is. This may get interesting. I will update you in a few days if not sooner.
Let's see how this pans out.
Also I am going to try Reddit for shirts and possibly Twitter as well. I don't know how those work out though.
