So, now I'm actively hunting GPS-traces for about a week. And it really is a lot of fun.
I did not have much luck with my logger first. The tracks were really awful. Then I found out that not the logger but the batteries were really bad. ;-)
So with fresh power I finally could get some useful tracks. Although there are some short outtakes now and then. Editing and tagging is most fun to me as there is almost nothing but black in my area. I often forget about time... :-\
