Biking

My father and me went biking today. I'm no bike addict, but I'd like to visit Ann in Janske Lazne. Going there by bus everytime would be too expensive.
The bike I used is mine and my brother's. It was in a bad condition and even after some repairing, it isn't very appropriate to a long trip, as it's a mountain bike...
Yet people around me were telling me not to do so, that I won't do it. So father proposed to go to a 70 km trip, so that I could see that I'd have troubles even with this.
Well, it was funny. I got lost after some 40 km. Father had the map, money, just everything. I was quite near Prague, but without the map, I was wondering there for long time. I was even roving in a forest for one hour (yes, with the bike)...
I was even going by highway for some time, to get the direction to Prague. When I finally arrived, I saw 100 km on the tachometer. I wasn't that tired (well, I am tired, but less than I anticipated), but I was terribly sunburned. Next time, I'll take a sun lotion.
