Does anyone know of any fuel /gas station ON the water near/on lake PONTCHARTRAIN or chalmette (again on the water though), that have 91 or 93 octane gas that i can put in my rxp-x.

i can verify that these locations on lake PONTCHARTRAIN do not offer 91 or 93 *(they all offer 87 octane or diesel only):

Sea Brook: (not sure, person there said 89 only though)
Southern Yacht Club (lakefront): 89 only
yellow gas station / restaurant, ON THE WATER, but right off Chef Menteur HWY by the bridge and venetian isles: 89 only.

Its a pain to keep pulling my rxp out of the water, going to a gas station , then launching again. I launch at bonnabel in metairie.
