Cool - I was at Glasgow for Philosophy rather than Theology. It was a wonderful department in my day - I guess it still is. Mary Haight and Pat Shaw are still there I believe, and Angus McKay is extremely interesting on the philosophy of religion. And of course there is the excellent Alexander Broadie. If you get a chance to hang out with any of them, I'm sure you would find it really interesting.
If you have an interest in evolution you will of course know the Hunterian Museum: a wonderful collection, excellent displays and really excellent staff who understand these issues really well. Jim Devine handles the education side - I guess he has to field the questions from the public. And Neil Clark is one of the most personable paleontologists you will meet - thorough knowledge of his subject and really good communication skills. Well worth looking up those guys too.
Have fun there - have a drink in the Aragon for me!
