LITS 2

Yeech.  I hope this post works okay.  I've created a monster of a LITS puzzle and now my Internet connection is all wonky.  I've got the images saved, but the Puz Pre link may give me issues.  Anyways, this puzzle is probably the hardest I've created so far.  Get ready to put your thinking caps on.  You'll definitely need to open this in its own window.

Puz Pre V3 link

Another tip:  If you go to the Puz Pre link, Go to the Display menu, and change the Cell size to Small or Ex. Small to see more of the puzzle at once.  It also helps with making the borders between regions appear thicker and easier to distinguish between them and the thinner grid lines.
