Tartan, thanks for taking the time to post your drawing...I'll have to give it a try.

I may try it. I can't follow my GPS, don't know if I could follow your drawing. I am directionally challenged.

Sounds like me but the picture helps and I've saved it. Will give it a try.

I use different colored washable markers to draw my lines. I follow one color at a time. It works for me.
