|Attack the "Yes" sign with a heavy weapon||600 RP|
Destory the "Yes" billboard
Although this is considered a story mission, it's completely possible to miss this mission entirely. By now you've probably seen John Seed's huge "YES" sign in northwest Holland Valley but what you probably didn't realise is that it's possible to destroy it.
Take a helicopter up to the sign and begin firing upon it to start the mission officially. You'll need to take down each letter of the sign to complete the mission. Alternatively if you made the trip up here without a helicopter then you'll be able to use an RPG to take it down (you can find one at the letter "E" of the sign if you didn't bring one).
