According to Wikipedia, after Apollo 11 returned from the Moon:
The command module Columbia went on a tour of the United States, visiting 49 state capitals, the District of Columbia, and Anchorage, Alaska.
The cited source backs this up:
Stopping at 49 state capitals, the District of Columbia, and Anchorage Alaska, the tour provided Americans with a unique opportunity to view and marvel at these historic items.
My question is, which state capital did it not visit on this tour? Given the reference to Anchorage and the relative difficulty in reaching Juneau vs. Anchorage, I'm assuming the answer is Juneau, Alaska, but I can't find any specific source for this.
