Puzzle 24 – Double Back

This is a Thursday double back puzzle. The black square in the center should not be traveled through.

Yeah, as you probably know, it is impossible to make a odd by odd loop puzzle without any black squares (by checkerboard). If only I had remembered this before getting most of the way through my first draft -_-.

So pumped for the mystery hunt! Only a month to go! And USACO happening this weekend! whoo, so much excitement.
