Farm Shows Which conventions/expos worth it?

[Petal to the Metal]

Which of the conventions and expos have you found to be the most valuable? I think it's important to stay up to date on the latest products and farming methods, but it's hard to take time away, so I need to be strategic about it.

The county and state fairs in my area have been the most useful for me. The state fair especially since you have vendors and farmers in one place from the entire state. More variety = more opportunity.
