Translation of knäppern

Thank you for writting back so quickly. I learned English when I was a kid, because we've always been in England during summer vacation, since my grandma used to live there when she was still alive.
On the second day we drove around Los Angeles. We were totally jet lagged (and so were our kids) and we decided to take it easy on that day. We went to Rodeo Drive as well as Beverly Hills. Both our children slept during the entire afternoon.
During the summer it can get pretty hot and humid here in Florida (strong winds from the south also happen, hurricanes), but I still think that Florida is an exciting and diverse state also in the summer.
