The town I live in is being considered for a Tyson chicken processing facility. $320 million is the cost. Another city is in the running, and a farmer wrote "NO TYSON" in his pasture with plowed earth. I would like to do something similar, but I want Tyson here. I have a 10 acres, a tractor, and a plow. I plan on putting the stock symbol for Tyson in a pasture, TSN.

Question: Should I put more, like + TSN or TSN and a checkmark? It can be difficult to make letters like O and Y with a plow, so I'm keeping it simple.
