Thing I found with all my solo's. When you get started make sure that you keep on your heading. I remember getting slightly lost and then thinking i'd found the valley and town that i was looking for and followed it. If only i'd looked at my heading i would have seen that I was 20 degress off!
So always check what you see out of the window with your heading to make sure the 2 correspond with each other.
You'll come back tomorrow wondering what you were worrying about..enjoy it
