Dave, where art thou?

One hour looking for David among the crowd in the MUUF (we had lost him while asking for the last caipirihna) and he was waiting the whole time in the car. Smart guy, a new YGT, with less than one month here and less than 2 or 3 times in Frankfurt, with no phone numbers from any of us, no more trains to come back till 6 AM, and he found the way back to the car, which was parked quite far near the cinemas (we had finally decided to see Madagascar before going to the riverside fest). The only thing, nobody knew he was gonna go there directly!!!! We were looking on the nearby tents, going back till the previous bridge or to the next one, and then separate in two different groups to go back to the cars to increase our chances to find him, and he was there waiting and freezing since one hour ago...
