Tuesday, Day five, third day on the water We were on a roll now from Mexican lake to Glen lake (lower, middle, upper), Optic lake. The area was beautiful, still no one else on the water. We seemed to have the park to ourselves. In this area you start to pass fly in cabins. At the portage sites there are small motor boats for the cabins. Some were just pulled up on the shore but others had nice ramps built for them. What we figured out, you could take the small boat from your cabin, go to a portage site. Portage your fishing gear and take the next boat onto the next lake to fish.
