Comet frustration

I spent about an hour last night in my heavily light-polluted backyard trying to locate Comet Schwassmann-Wachmann—to no avail. I swear I was looking in the right place, according to the May 2006 Sky & Telescope charts, but no dice. I started a bit early and had to wait for the appropriate region of the sky to rise above the treeline across the street. But I figured it should have been a short hop away from alpha CrB, right? And according to S&T, it ought to be around Mag 7 by now. I just didn't see anything that looked like a comet. I figure one of the following went wrong:

1) I was looking in the wrong place (not too likely)
2) Light pollution washed the sky out too much
3) The comet might be largish, making for a low surface brightness
4) The TV-60 just doesn't have enough photon-gathering power for this object

or some combination thereof.

And to top it all off, the smell of lilacs near the deck was so cloying as to induce mild nausea. I never have cared for perfume.
