Aerial Photos

I printed out aerial photos of our training areas, they are fairly current and good enough for our sessions.They are good visual aids for handlers and the throwers I hope they will reduce the confusion. of where to go when sent out into the grass. If they use the chalkboard in a locker/training room so why not here? I marked the mown grasses from the unmown. I do not see anything wrong with assisting the throwers if it will make their job easier and make it clearer for the handlers where they are expected to send their dogs. This should keep the training session moving and reduce any arguments that could occur when throwers are unsure of the direction they are to throw.
