I tend to take landmarks like this totally for granted! Haven't been inside our local cathedral since i moved here 2 years ago, and it's only a 5 minute walk away!
Hope your back clears up swiftly!
On the bright side, think of all those little muscular tears that are getting time to heal.
Most old churches have something interesting to see. I like to feel the sense of history.
The back thing is just annoying, but I timed it well with the weather being crap. I've done a lot of walking today too and it has not been too painful, so I must be on the mend.
