When you buy GPS you download the track and then you can go anywhere.
Right? No. WRONG!
You should also use it, follow it.
I did not follow, I slept over the TURN RIGHT.
And instead of getting the normal way to the peak we got to go unused route.
Actually we have created the new route today - ALTERNATIVE one.
Eventually we did not reach the peak but we got home healthy and happy.
What else is needed when you go to mountains?
