The revenue from selling exhibit space is only one revenue stream; Reed also makes money from selling tickets to the attendees of the show. My guess is that word is spreading through the outdoors community and that attendance will be proportionally affected by the withdrawal of key exhibitors.
how many are presold?
How many there will be fat old unionistal elderly looking at RV’s?
How many there will be fishermen who hate hunters in general?
How many will be reporters spewing MSM propaganda?
Exhibitors are already invested, attendees are not. It's easier for an attendee to skip than for a vendor to skip. Just saying, I think attendance will be off by a bigger fraction than the percentage of boycotting vendors. If 15% of the vendors boycott, maybe 25-30% of the attendees will.
And some of the attendees now know the name "Reed", and will be looking for it, as long as they live.
