Notes

The moon's phase or fracillum (percentage of the moon illuminated) doesn't vary much with location.
A full moon is not just bigger, its much brighter. A half moon ('50%') give less than 5% of the illumination of a full moon. You can walk with a half moon if its high in the sky (after dusk for a growing moon, before dawn for a shrinking moon).
Sky glow (light reflected by air or clouds) from nearby cities, and especially snow on the ground also effect light levels.
Times will vary a few minutes, as (i) these figures are for the centre of the county the walk is in, and, (ii) if there are hills on the horizon.
Of course, you need a cloudless night as well!
