Come on! You know that number. It's been stuck in your head since 1981! If you don't know it, ask your dad, or maybe your kid, or a cool friend who still listens to 80's music. Then listen to it, and sing it in your head (or out loud) all the way to the cache. You'll need those numbers when you get there. The cache is on a little side trail off one of the main trails through Royal Roads Forest. The coordinates bounce around a bit with the tree cover but don't let that stump you. You'll get close enough to figure it out.
Have fun!
