Flying in South Carolina

I am now down in South Carolina crewing for my father at the Region 5 North contest in Perry. He offered me to fly the practice days, then he will fly the contest. On Friday it was blue but we had good lift to 5000ft and once got to 6000ft. I flew 306km Friday flight. Saturday was not as good. It was blue with high cirrus moving in. I didn't get much more than 4000ft for most of the day. I stayed much closer to the airport and did 192km Saturday flight.
