I'm loving your journey. thanks so much for sharing.
You'll love Flagstaff.
If you head up to Lowell Obs, I'd like to hear your opinion of the talk they give inside the big Obs. ( I walked out a quarter of the way through after they said the LMC and SMC were just star clouds not galaxies )
Otherwise I enjoyed the displays, was in awe of the mausoleum and was grateful to be allowed to image through the Clarke Telescope.
Take the time to go to the Galaxy Diner too.
There is an Apollo Tree at Flagstaff Jnr High you can visit too, after school hours.

The trees are grown from seeds flown on the Apollo 14 mission.
