Sounds awesome. Isn't Windy Lake nice? Not easy, but so pretty. Laurentian's trails are great too. So nice to have them right there on campus. Maybe Milton will take it up as a Sudbury activity - and even try it at home some day. Good for you for getting him out.
The dark pines at Windy Lake are perfect for a foreboding scene in a movie!
Student rental + trail pass at Laurentian is $10, so hopefully he can get a few sessions in.
