I love the trekking on foot as much as a magic carpet ride on Bob's sweet flats machine. There are some spots where I wished I had a yak handy but not many. I won't go into details but primarily where the road access comes to a channel that doesn't open up to flats for a few hundred yards or to reach an island or point that requires a long circular wade pattern, etc.
On the topic of footsteps I am extremely cautious about where I make footsteps not because of visibility to other humans but I don't like to mar the paths of moving fish with mudlines in these slow moving tides, add visual distractions, or change the way bones react on their cautious approaches. It bugs me when people track right through the lanes.
