wow, don't limit to shooting and stuff like that. You can spend a month sightseeing in London alone. Actually, you can take the tube to within a block or three anywhere in the city. The Crown Jewels are a must, Madame Tussauds (sp?) is great. Westminster Abbey and the cathedral must be seen as well. If you can get to the gun shops, have fun. Take MUCH money. The pound is still about two to one to the dollar and prices are about double US prices. What I can buy in the US for $100 costs well more than 100pounds in my experience, sometimes up to 200pounds depending on what it is. That said... enjoy your trip. I've been four or five times and can't wait to go back. I really liked Scotland much more than England itself. I think we are going to Ireland in spring of 09... at least I hope we are.
