Turns out that it's real easy to grill on my roof. Shame on me for waiting three years to test the theory, especially since it was a piece of cake. The grill came from the Rite-Aid on the first floor, a steal at $7.99. At first glance, it was a true piece of shit, but it wound up making a mean burger and breast of chicken. Added bonus: Even with the wind doing its worst, I didn't set the roof on fire.
