"the $6 for a 30 cent baked potato seemed absurd."
I shall look forward next year to the far more budget priced 'Berson's Taters' stand.
lol
The place has to buy or rent all the equipment and booth, hire staff to bake them, keep them hot, serve them, provide the means to eat them, have appropriate condiments handy, clean up after them, maintain all pertinent health and safety standards etc.etc.etc.
It ain't as cheap and easy as one might think and I for one am THRILLED not to have to provide food for the picky masses. Suffice it to say I don't attend AirVenture for the foodie experience. And the vendors beat heck out of cooking myself or eating something grim out of a can from WalMart.
