Locations

Hey there! As you can see, I am new to this forum, but not new to being interested in Columbine, heh.

Anyways - I am from Europe and I'll get to visit the Littleton area next year in spring. I want to (discreetly, of course) visit as many related places as possible. Has anyone done a similar trip and can point out some places to me? I tried to see if someone has talked about this using the forum search but didn't find much.
I gatheredsome addresses, like the school and memorial obviously, the former Blackjack location, the houses the boys lived at (will obviously not stop there or anything, just drive by, I really wouldn't want to bother the people there or offend anyone).

I would love to visit the Rampart Range area E&D were at, but have so far understood that it is too big to tell where they are? Or does anyone now?

Also on my list I also have the steakhouse they had their last dinner at and got the address for that.

Does anyone else have some interesting locations and the according address?
I think I read the purchased last-minute items at 'King Soopers' in the morning? Is that correct, and where would that be located? I saw multiple ones on maps..

Thank you and I hope I don't get trashed for these questions.. u.u
