I went to a local dog show as a spectator and did not pay. The dog owners did pay. Think about what it would be like if you reversed it. You'd have a bunch of cars and no spectators. Not much of a show anymore.
Ya...I guess...
Out here for instance the Route 66 show charges like $65 to show a car....I'm like NO WAY.....! I'll leave it safe in the garage for free...
