Navionics will tell you where they are at since you don't appreciate the help of others.
I do appreciate the help of other which is why I requested the advice of people on this forum. From the post of Notaguide I took it as he was calling himself lazy and he could find the info so I should be able to find it too.
I had found it but as I stated "Thanks for the link but I found this already. The link to http://www.lonestarlakes.com/map/guestmap.php?map=lewisville
is no good.".
Perhaps you should read through a poster's statement before commenting. I do however appreciate your response.
Also, being that this is a "boat rental" trip I seriously doubt the pontoon will have hi-tech graphs such as Navionics.
