Previously as an OEM level consultant, I found little value in it myself, or as a dealer beyond getting some product demos.
As a vendor, even less valuable.
Sometimes there are some decent takeaways in the break out sessions, or you meet some awesome operators, but in large I don't see it being a worthy investment of time or money today.
Maybe I will be wrong. I look to be convinced that conventions outside of NADA have value beyond vendor sourcing.
