I'm no fisherman, I'm afraid. Wouldn't know what to bring or where to start. I've cleaned way more than my share of fish that others have caught, though. Grew up on waterfront. Come out and hike a section with me. If you catch 'em, I'll clean 'em and cook 'em.
If the MPD's are short enough that I get bored, I know what to do. Hike farther.
I really don't know how to judge MPD on this trail. I'm accustomed to hikes that have either a lot more elevation change, or a lot more pushing through brush, or loose and sharp rocks underfoot, or all of the above. I read that NPT has roughly 10k feet of elevation change in its entire length. I've had that amount on 14-mile loop on a weekend trip, and that loop included a couple of quarter-mile sections that averaged 100%+ grade. A soft and level treadway will be a novelty to me.
