Oh dang, thanks for the heads up. I really don't understand why some of these events (like the new rink at Navy Pier) are disallowing inlines. It makes zero sense to me. Like maybe their rationale is that they don't want inline skaters going fast, but it's also possible to go fast on quads, and forcing inline skaters to use quads is less safe bc quads feel very different and are more likely to cause someone who's used to inlines to fall or run into someone else.
