How Do I Link to a Thread?

I'd like to share a link to my trip report with friends, but I noticed the address bar only shows www.backpacking.net/bbs.html. Is there a way to form a URL that will get them to the right place with one click?

I figured out that if I look at my list of posts (My Stuff > Posts), I can copy the link from there, but I'd still like to know how to do it more generally.
