I might be making a trip in late August to Aberdeen for a relative's wedding. I'm pumped but have no idea what to expect there. We don't necessarily plan on visiting any other part of Scotland or the UK, but the wife and I will probably turn this into a week long vacation so suggestions are what I need. I'd love to find good breweries and places to get bottles to bring home. I searched this forum and didn't find much info, except that I'm not supposed to tip in a pub? Which is weird to me... Also, what's the preferred method of local and/or long distance transportation if I don't have a car?
