I am looking for a map source here in the lowermainland. I tried a funny store in Richmond but no joy. I previously ordered by mail but am in a bit of a pinch for time.
The mape are for work and must be Canadian Topographic 1:50 000 or 1:250 000 for dead reconing as well as field survey.
I do not use GPS or Backroad Map Books as they are not for reliable navigation in the field. Any map or GPS plot of Elaho Valley would be good as well.
