They are pretty quick to lock TR's...personally I wish they would wait a while longer...but they lock them up pretty fast to keep the board a little smaller and more organized.
But it is easy to get one moved back to the open board again...just PM either of the moderators and they will unlock it for you!
To keep it from locking up, just post occasionally and tell us you are still working on it...or tell us what is going on in your world or anything to just keep the conversation going a bit until you are done.
The vast majority of people that are able to finish do it fairly quickly upon getting home. Either take lots of notes during your trip or take a BUNCH of pictures...even pictures that don't really make sense to use in the TR, but would tell you where you went next...like a picture of the sign for the ride or anything. Anything to tell you what you did next.
Writing a TR is a lot harder than it seems before you go. Once you get back - life just seems to creep back in and it is harder to find time to do it...and most people really want to do it well, but uploading pictures, copying and pasting, writing the text, etc - is all harder than it seemed it would be. But is SOOOOOOO worth it! The finished product is something you will cherish long after it is read and enjoyed by thousands here on the DIS.
Some kids are also sick when they return and it just doesn't make sense for the parent to spend time ont he computer when they could be spending the time with their sick child.
For some the memories seem too hard to summarize and for some the trip was not quite what they thought it would be...so there are a number of reasons why a TR is never done.
But no matter what! Stick around! Keep posting here, keep answering questions, don't worry at all that people are wondering where your TR is...just keep coming and eventually you will either get to where you can write it or not, but we still want to see people around no matter what happens.
Woo Hoo!!! Have a blast!!
Awesome way to celebrate that milestone!
