I'm the bean counter of the group, so I guess I'll take on the scoring duties. I've got a special calculator I'll bring along too.
When I first started out bean counting I used a pencil and a big eraser.
After I got my feet wet a little I graduated to a mechanical pencil with a little eraser.
Then I got a little smarter and more experienced and switched to a bic pen.
Finally, I got real smart and the top of the heap, so now I use a feather quill/ink well and a little sand dust. NO ERASERS ALLOWED. :D
