Getting from Roosevelt to Fremont is challenging enough, let alone Leavitt Meadows, so definitely pack light. There are strong rainbow trout at Fremont, but finding a place to cast around the perimeter of the lake can be challenging with deep mud and rocks (bring waders).
I did this hike when I was a boy scout in the early 90's. It is a beautiful hike, and a nice place to stay a few nights. We ended up catching over 40 trout that weekend. Not many people were out there, and the start in Leavitt Meadows has a nice mountain stream to hike by.
