I just had an epiphany... first off, WOW that place was HUGE if it used to extend all the way to JJ Fiddlesticks! Second, and more to the point, have ya ever noticed that JJ Fiddlesticks (which was one of the boundaries of TSL apparently) is very close in location to a certain other treehouse-themed area? I mean, even the lore is the same (that some kids built the place to play in). Would it be a stretch of the imagination to say that this certain other area (look at my username if you haven't figured it out) was originally planned to be some sort of extension to Tom Sawyer's Landing (or at least another area connected to the toy store), but that the idea was scrapped very shortly before building? Just a thought.
