2 hour to find the way

you know guyz, yesterday, me and my friend try to find the way home by our self (with riding bike). and by using our map and intuition, of course, we finally found the right way. it almost 2 hour. (the normal time is just about 30-35 minutes)

Haha,
But "learning by doing and finding the concept through practicing is a good way"

^_^

But the problem is, we can't remember it. So we should follow the instruction again. and make a new map again. :D
