I arrived in Budapest this morning. I slept all afternoon.
I came to the conclusion that my iPad handlebar bag was too much weight too high up, that the bike would not ride well. So I am using a smaller conventional handlebar bag, and I will put the iPad in my panniers.
I am pleased so far with the iPad as a travel tool. The available maps are not nearly as detailed as printed maps, and sometimes misleading, but I have managed so far. I changed my route to skip Zagreb and go directly from Hungary to Slovenia. It is raining today, but the weather report on my iPad weather app says that tomorrow will be sunny here and Monday will be sunny on the Dalmation coast.
People are raving about the beauty of both Bohinj and Bled, but I don't have time if I am going to both Montenegro and Bosnia. Always save something for your next trip when you travel.
