O/G Rocksim-

[Andy Greene]

So I got some clear on my Minie Mag , and while waiting for it to dry I figured I would build a sim and see what we can get away with motor wise, when low and behold - Bamm ,
No interwebs - zang it man. being a resourceful BAR - I Broke out the old school Chalk-Sim Calculator , you younger guys wont know about this stuff- but read along anyway
The wife was none too happy about it , but you do what ya gotta do in tough times right
You older BARS have one of these laying around somewhere Im sure you havent used in years, but it still works, just so you know,
Im gonna go finish dinner now

Ah yes, I remember those. They measure time with a sundial and mass in "very small rocks".
