Well, imagine 4 or 5 screens of stuck threads, which is what would happen if there were 50 or 60 of them.
Stickies work when they are very few in number. Three or four in a forum, max.
Look at the Rallies forum index, where you can specify the state/province at the top and it will just pull up those listed with that prefix.
The problems with doing something similar to the Camping/Campout Reports will be how to determine the prefix, what to do about trips that cover more than one area, and possibly how to assign codes retroactively.
I realize you and I are really talking about two different things: I want to impose browsing order on a forum we already use, hoping it will become something similar to what you're after, which is travel descriptions and information organized by location.
