Ever see LakeMasters on Enid or Grenada this summer mapping, it was as good a time as there has been in a long time to map both lakes but I never seen them at Grenada. Before anyone gets started on the guy who mapped Butla and Sardis, this is not on him, LakeMasters was supposed to send one of their mapping rigs down to do these 2 lakes, just never saw them. I aint buying no card until the 2 lakes I fish the most have been mapped, waste of money but sure is aggravating that Navionics just stops where the lake is still 15 foot deep on the flats at summer pool!!
