basic maze problem with turtle

[baujacob at gmail.com]

Hi everyone, I'm trying to create a simple maze program. When the user finishes the maze, I want to print in big letters "You Win!" and when the user hits a wall, I want the user to go back to the beginning of the maze. The problem is "collision detection" which is an advanced topic and I'm only in a beginning programming class. Is there anyway I can force the user back to the starting point when the turtle hits the wall? Thank you in advance.
