One thing I forgot to share--I love using the "follow the route" feature and you can see where I have four routes on this page. Using the Mosaic capability, I want to make sure my routes go over any kind of structure the crappie may stop at while moving upstream to spawn. There are places along the creek bank that are just dirt, but there are rocks, stumps deep holes, etc. that will hold crappie on their travels. I want my boat to travel right over these places and Mosaics allows me the ability to be very precise in planning my fishing routes.
