For the purpose of this guide, we have assumed that you know how to fly cast. There are also some great books on casting technique which you can usually purchase at your local fly shop. Even if you feel fairly secure about your casting ability, we strongly recommend that you take a few casting lessons to perfect the "double haul" as well as your casting accuracy and technique. Most importantly, pratice casting (in the wind if possible) at least 10 minutes per day the week before you arrive.
If you have troubles with your cast while at the lodge, Casa Blanca's fishing coordinator can help you make a few adjustments.
