   Format: MarkdownItexhave added to _[[associated bundle]]_ an exposition, [here](http://ncatlab.org/nlab/show/associated+bundle#InGeometricHomotopyTheory), of how in a context of $(2,1)$-topos theory, associated bundles are naturally thought of as homotopy pullbacks of action groupoid projections. This is from one subsection of what I am currently typing into _[[geometry of physics -- representations and associated bundles]]_. It may need more polishing, but I need to interrupt now for half an hour or so.
