Air Show Tents

QUESTIONS My only question is that in years past you used two more 40 X 60 in the grass for shade - this year it looks like you are using all 20 X 20's - will these really be on the tarmac or might they be in the grass area between - the way it looks you will use a lot more blocks this year. The larger tents are usually more economical as it is quicker to put up one large tent than multiple small tents but we are flexible just wanting to be sure when we submit the bid. They are in the grass areas and can be staked into the ground. We went with more smaller tents versus the large tent to cut costs.
