Here is my suggestion it might not be an "easy " one to do, but it could be worth considering.
Restaurants would be a great target for a Hardfork Series stunt. There is one thing that restaurants have constantly on the minds of owners and managers and that is; “how to make the eating and payment experience more enjoyable for millennial customers” . Crypto currencies would fit well into the payment aspect of their concerns.
The National Restaurant Association has their annual meeting in Chicago in May. I propose that Hardfork-Series find a way to get the food caterer for the main dinner event to replace the normal forks at the dinner with nice “hard forks” that have the piercing prongs of the fork split widely apart by about two inches, so there would be two prongs on the left side of the fork and two prongs on the right side of the fork.
HFS would need a booth at the trade show, the napkin the fork would be wrapped in would give the booth # and invite them to come by and discuss the series and crypto currency payments for their business, along with an opportunity to take part in a “national hard fork day” when the series kicks off.
