Yes honey burns work in curtain conditions, but only in the direction of the wind, just setup looking in the direction of the smoke, I use a large coffee can and a small can, cut out some tabs on apposing side of the small can to raise it above the large coffee can(the small can fits into the large can to fit the can of sterno under the small can, leave around three inches for the sterno stay lite. I used a heavy coat hanger to carry it,like a paint can, cheap and works well, just don't put to much honey in the can, or it will over flow and go on fire, before using the burner, clear the area around to be safe.
The last time I used a burner I was with my father, we burned honey for a hour, sat another hour after, we saw no bears, so we headed out to make some lunch, walking down the logging road bumped into a black bear on the road, when he saw us he ran like no tomorrow, he was like a black blur, if we waited a Little longer Mr bear would of showed up, we were also at a bait site, figured it was a good idea, since we were not seeing bears and they were eating the bait, just when we weren't there;) Oh well keep patient and good luck.
