I'm definitely planning to attend.
Also, if you haven't finalized the schedule yet, I would highly recommend stopping at the Bertram Road bridge just east of Cedar Rapids. It's a really cool wrought iron truss bridge built in the late 1870s and one of the oldest bridges in Iowa still open to vehicle traffic (and one of the few 19th century bridges on a paved road). However, that won't be the case for much longer because it's scheduled to be relocated to a pedestrian path this fall so that a new bridge can be built in its place, so now would be a good time to visit it.
