Drafting has begun

I've always found it a good idea not to let the field checking get too far ahead of the drafting. The more time that passes  the more difficult it is to remember exactly what I drew on a particular day. Is that a boulder or a dead mosquito?

And I shudder to think of anyone else trying to interpret my field notes. The resulting map would not be useful. Orienteers would find trails where there should be roads, dark green where there should be open, boulders where there should be dot knolls.

One thing that I do with vegetation that helps a lot when it comes time to draft is to use the last two digits of the IOF number for the vegetation. I have a list of the numbers for that and other symbols taped to my board. I don't have it in front of me right now, but I think all the vegetation sysmbols begin at 400. So in the field I draw a line around the area and then label the interior with the corresponding number, like 9 or 11. I do the same thing with all the different road and trail symbols, using a solid black line for each and labeling them with a symbol number. I also do this for any other symbol that might be misunderstood or confused later. This reduces the chance of error when I draft.

So now I am up to date on the area north of the big power line along Flat Rock Road. That means about 0.7 sq km has been field checked and drafted.
