My wife and I are headed to England in a few weeks and of course I will take 1000 photos. I can't decide whether or not to hassle with a tripod or even a monopod. We will be spending some time on a small tour bus (actually a 16- passenger van) and I don't want to appear too obnoxious. I know it may be wet, so I have purchased a "rain coat" for my D60 and short zoom, but at least I can put that in my pocket if it doesn't rain. Suggestions?
