If I knew where your desk was you would have your report on it! Failing that, I will enter my report here!
I have no problem with the "big guns", I enjoy their playing. I think my continued presence at the jams supports that. I wouldn't spend time somewhere that I did not feel comfortable.
What I would like to see is a small group of less than "big guns", "little pistols" if you will, be able to get together and practice together, so that one day we too may become big guns. I had an opportunity to play at the Picnic/Jam with Gern and a few others...I even took a lead for one of the songs we played! That built my confidence immensely...but I KNOW that I cannot keep up with some of the bigger guns, yet. Maybe one day, maybe my version of "Old Time" will NEVER blend with what we hear at the Bluegrass Shop, but what is important to me is that I have fun doing what I do.
As for a specific answer to all your points:
1. Being able to play with the "big boys" is an opportunity.
YES, It is...just some of us 'Ain't quite ready for prime time'.
2. Don't agree? Then try to find another group like we have with these big guns.
Exactly right, the group is unlike any other I have ever seen or heard.
3. It is an open jam. Always was. But the thing that built the popularity was having the "big guys" hop in.
Yes, the BIG GUYS did popularize the jam and keeping in mind that one of the reasons for the jams is to promote business for the shop, this is a good thing!
4. The rules, I think you refer to (?), are common courtesy for jams.
I would agree that there needs to be an observed 'ettiquette' for keeping some sense of order.
5. The fish fry was 50% organized by the "big guys."
Didn't know that!!
