Hey jrodrod. Thank you for your question. My drop zone is near Madrid in the center of Spain mayland, very cold in winter and very hot in summer. In summer i can do 10, 11, 12,... every sat, sun and 15 during weak days. My own record is 69 in one weak and 17 in one day. I am 59 years old. I have almost 12.000 jumps and exactly 9.866 tandem jumps. I hope to do my tandem jump number 10.000 in september. Crossing fingers !!!
