C Get the Green Top
=========================
Boone will be scoping out a green top for the ranch. He will tie a rope to it,
and he'll instruct you to pull it down. This is an extremely simple button
mashing mission.
In fact you only need to mash one button, X. You have until the timer expires
to charge the meter on the screen all the way to the top. Just keep mashing X
until its fully charged. Sometimes the screen will move upwards away from you
and show the green top shifting position. For this brief period you may stop
mashing, but once the screen shows you again, start mashing. Once you're done
you have a new addition to the Skate Ranch.
lol all he had to do was mash the X button
