Fort George may well be worth a look, the pictures I've looked at seem interesting.
The House of Bruar's tartan jackets have impressed me, however, it's ashame they don't have any available for men!

I've heard that Inverness is currently replicating what we had down here a few weeks ago, but hopefully it will clear up a bit and hopefully it wont drop below anything I can't handle in a kilt! I'll be taking 2 or 3 heavyweight kilts with me and will more than likely have 4 or 5 layers on, also.

We mainly want to explore the history of the area - castles and if there are any monuments. We'll be sure to pass the Cameron Highlander's memorial and several others when going around the town centre.
Also, are there any pubs with kilted regulars (or at least kilt friendly) for a quick pint around the centre?
