No camping at Lee lake, but Police outpost would work for you (watch wind reports)
Probably don't need more than 9ft leader for pike...not defined as a shy fish.
When bobber fishing you need to determine the depth of the water where your flies are. Then you need a leader at least the same length as the depth. Depending on conditions, you may be fishing right at the bottom, or anywhere up to a few feet under. You have to find where the fish are feeding. After about 25-30ft, it is time to use a full sinking line and fish vertically.
