[ARDF] [TexasARDF] 1:10000 vs. 1:150000

[Matthew Robbins]

My question back to you would be: What scale is usually used at
Bastrop?  A lot of times the map is made for one or the other scale.
There is a convention that the 1:10000 printed map is supposed to be a
pure 150% print of the 1:15000 map, but that's often not the case,
especially for older maps.

If there is a lot of detail, 1:10000 is really nice.

Another thought is that maps usually have border information, like a
title, legend, copyright, mapper, revision dates, etc.  Any
experienced competitor can just cut away the entire border and leave
only the actual map.  I'd propose that a 1:10000 map only, no title,
legend, etc, should preferably fit on 8.5x11.  If that overly
constrains your course, then the two options are (1) jump to 1:15000,
or (2) tell everyone how big the mapboard needs to be at 1:10000.
(Typically a map of the border only is posted, with the map itself cut
out).
