sO, i HAD THIS DECK BUILT

[QueenBee]

Do your chair legs ever fall into the cracks between the boards on your deck?

Nope. Not much of a gap between the board of the floor.  Barely a half inch or so.  The guys who designed it and built it were friends of Mr. Bee.  They built us a ramp on the front of the house, too.  The one who "designed it based on what I wanted, took his measurments and drawings to Home Depot and had them do a 3-D printout of it.  That determined how much lumber to buy.
Maggot, if memory serves, you do stuff like this, don't you.  I seem to remember you helping out LC (RIP) with something, but do not remember what.
