You saw tens of thousands of riders?
That anecdote just doesn't jibe with the throughput numbers -- that's why it seems like a flex, it's grossly inflated.
Now before we go into pedantry and you talk about how 'riders' meant 'all willing participants who are sitting in line' , fine -- i've been to SEMA and I understand those crowds , but those aren't riders. It's a misreporting of the situation, and frankly it seems intentional.
