Once, you could walk into any five-and-dime store, or even any drugstore, and get a pack of construction paper with a large selection of colors. (I should know--doing things with construction paper was one of my favorite hobbies in childhood).

Now, however, Staples and the drugstores near me have proven inadequate in this respect.

I was hoping to avoid the art store route, since I only need the construction paper for a temporary project (specifically, for mockups of proposed Raptor banner designs) but I suspect I'm not going to find what I need anywhere else. :-(
