absolutely fun! i was the only 1 one who booked for the slot, but they were still willing to hold the tour for me. thankfully my hostel mate joined me last minute!
the lady boss made sure we were safe and gave clear instructions all the way. i wanted to book the city tour too cause it was just sooo awesome, unfortunately they had no more slots the next few days i was still in hamburg =(
in any case, it was exhilarating to travel 90km/hr at one point on a real street (did the country tour) where im so close to the ground, feeling the wind smashing into me, i suddenly thought maybe that's why racecar drivers love to race! cause it felt so exciting!
