Mind the Fractal Puzzle

"Traditional mazes can always be solved by brute force methods.  Every path that is not the correct path is either a dead end or a loop of finite length, so given enough time, one can explore every path of the maze.  Fractal mazes, however, have wrong-way paths that are infinitely long, making them neither dead ends or loops; they are much harder to recognize as the wrong way.  The fractal maze is fractal because it has identical copies of itself embedded within itself, which can be entered.  In the maze below, you must enter them to solve the maze.  Begin at the MINUS and make your way to the PLUS.  When you enter a smaller copy of the maze, be sure to record the letter name of that copy, as you will have to leave this copy on the way out.  You must exit out of each nested copy of the maze that you have entered into, leaving in the reverse order that you entered them in (for example: enter A, enter B, enter C, exit C, exit B, exit A).  Think of it as a series of nested boxes.  If there is no exit path leaving the nested copy, you have reached a dead end.  The eight pins on each of the sides of the maze represent these connections to the outside of each copy (obviously, you cannot go outside of the main maze itself.  Watch your entrances and exits, and go from MINUS to PLUS. This is from a work in progress, 100 Enigmatic Puzzles.
