Quoted from Tektune:

Suggest using a drop or two of TriFlow (Teflon lube) on the ball shooter rods, some of them were pretty sticky by the end of the day (ie. The DMD Playboy in the back corner). The teflon is non greasy and lasts quite awhile.

Quoted from usandthem:

The pitch on the DMD games was pretty inconsistent. I'm no pin wizard and typically don't notice a few degrees here and there. For example, Congo felt spot on to me. On the other hand, certain games seemed a bit "floaty".

Quoted from mot:

I was the only camper this year, but it was great and I will do it again and try to bring as many people as I can.
