Thilo, a friend from Germany arrived on Saturday in San Francisco. After cruising around the Bay Area with a rented convertible we were on the watch for some more fun.
We stumbled across the website of iFly, a indoor skydiving facility. That looks great!
Unfortunately, they are booked up until Wednesday. I’ll let you know how fun this is!
Update: Although it was kind of expensive (2 mins for $49) it was awesome! And it is harder than it looks. 
It was awesome!
Thanks for the nice stay and meet me some time in berlin.
Oh yes, I will! Perhaps at the end of this year. Thank you too for the great time!
