My knowledge of your area is pretty slim, but aren't there martyrs' shrines or relics nearby?
If you like gothic architecture, you must visit the cathedral near me the next time you're in this neck of the woods. It's neighbor cathedral in NYC gets a lot of the attention, but it is IMHO the more beautiful of the two.
In New Orleans we have two National Shrines: one to Our Lady of Prompt Succor, the other to Blessed F.X. Seelos. I’m not aware of any martyrs (the indians hereabouts were not especially violent towards missionaries, as far as I know).
Also we have an uninterrupted bike path atop the Mississippi River levee, all the way from Baton Rouge to New Orleans — ideal for foot traffic, with over 1M Catholics within a 100-mile radius. With proper planning and sponsorship, it could make for an impressive turnout.
Thanks for posting the link to the pictures. They were very slow loading on dial-up but with Handel’s Dixit Dominus on the computer speakers, well worth the wait.
I can only imagine what the high altar was like before the wreckovations of Vatican II.
