After flying a Cub 550nm from Memphis to Oshkosh, I'm not sure I can remember all the stops!
KUNU (Juneau, WI) was our last stop prior to OSH. The staff was great and very helpful. Lineman (Keith) was awesome. Fueled our Cubs, added oil and fuel, correctly and about anything else we needed. He was knowledgeable and careful. Inside, they had a spread of cold cuts and sandwich makings and were selling ice cold 20oz softdrinks for $2 or water for $1. Fuel price was around $5.50, don't recall exactly.
They also had a laptop out of folks to check weather or read the OSH Notam.
My brother accidentally left his iPad laying on a table at the FBO. Keith brought it up and delivered it the next day. I ran into him later at the Steve Miller concert and we BS'd for several minutes. He is a young guy and loves aviation and it showed.
