Hit a Roadblock!

I'm revising my newest novel, The Go-To Girl, and seem to have hit a brick wall. A critiquer from Critique Circle told me she couldn't picture the setting of one of the scenes, so I want to rewrite it to include a better description. I keep avoiding doing it, though--to the point that I find other things to do than write.

For instance, this afternoon I'm going to work in the yard! Scary thing to pick over writing, huh? But, that's how blocked I am. The best I can do is promise to think about the scene while I'm gardening. Or, maybe I shouldn't think about the book at all...
