Traveling to different sites with limited time it has been the most enjoyable when scheduling a dual x/c lesson. The instructor is more of a guide but you will pick up s few things. The time to be signed off for solo takes as many clock hours or more than going out on a 4 hour instructed flight where you will see more and fly more. Most instructors are pretty quick to discover the student ability and promptly stop instructing and start chatting as you fly around. Local knowledge is helpful and often you are able to fly a nice 2 place. Skipping s bunch of paperwork which might not come through in time is another t a son to go dual.
