#A46: The Longest

 This might be the only puzzle type on the calendar that I was actually somewhat scared of setting. I like the solving logic, but the elegant simplicity of cluing makes creating a puzzle really hard. I expect to be busy for most of today, so I've only decided to make one puzzle. I found this grid on my seventh attempt at making a small themed board, and I think I managed to make it flow well through my usual style of setting despite a hunch that the easiest way to set might be to work backwards from a simple solution.
