Improving dgrr

[Herblenny]

I did have tuning class one year and I might try to get something like this for next year if enough interest is given. But that would require one of the vendors to actually come out and do a class... by what I have heard from some in the past is that they themselves wants to just come out and relax a bit.

I'll see what can be done for the 10th anniversary... but demand needs to be there..
