If you load his waypoints into your chartplotter, and ignore ones that may be there either from a prior charter or perhaps the charts themselves, you should be fine. Just be sure to visually confirm whatever buoys are in place as you head in. The chart isn't necessary but I plan to get one and frame it.
Hah, i have one of Walker's charts framed along with his Cow Wreck print D Office. The chart is in my office and the D Office is in the kitchen. It has great colors
