We do many workshops here too, different topics, but nothing with the common sense, been there done that in the past, type of advice as you seem to get there. Not saying that I don't try to learn something every time I go to one, because I do. BUT, there is more of the bland, feel good type stuff it seems to me. Not as much of the nitty gritty, "you may not want to hear this BUT " , type of stuff. They will have some different experts in some of the different things you mentioned... yet there are not near the "age" of people who have really lived through it and then learned from it and are trying to pass it on. There are many that are younger, with good "college" educations, but I look at some of them and they have not been through some of it and really don't have a good grasp on it. When they are asking me during a meeting for my opinion, and I have only been here for 35 + years, that tells me they just don't have the practical knowledge. I DO NOT consider myself an expert in anything... and I haven't been in it as long as some of the others.
Just completed a 6-7 week course on beef cattle management... and sorry to say I learned very little from it. Most of the stuff I have been "preaching" or doing for as long as we have had cattle. I don't want to hear all the "feel good " stuff, I want real examples and RESULTS, whether they are good or bad. And I was very frustrated to have them parroting this or that person, and could not answer all the questions that were generated.
Our Va grasslands group has a big day long meeting in Jan every year; 4 different areas in the state, same program. One year we had Temple Grandin speak. It was packed. I have read some of her books, and have tried to make some small changes in the way I do stuff according to things she points out; especially with cattle flow and their particular habits. But I want to hear about the down side so that I can do what I need to do to prepare for it and to take advantage of the upswings when they occur.
Sounds like the group you have there is top notch.
