Was 17 then, and what strikes me most about it is that neither I or anyone I knew was in the least bit put off about going to town because of it.
Wasn't in town on the day but my now wife was in superdrug she tells me and heard and felt the explosion, she also says the confusion amongst shoppers was odd, with some resenting being told to leave the store and go home presumably as they didn't know what was happening, and others panicking immediately.
Incredible the regeneration since, I'd be hesitant to say it was because of the bomb not wanting to give them any credit at all for what our wonderful city has achieved.
