OP. Got to Kansas and walk 100 miles.
Visit some flat earth sites and just watch the information. It's ok not to believe ..we are always being lied to. But when you figure out that you want to visit the truths you are starting to be set free. That is amazing. And the flat earth always makes more sense than a globe. Globe just doesnt cut it. More proof of flat earth then globe. There ar no pics of a globe but plenty of flat earth. When you get the truth there is no going back so I'm sure your friend didnt change his mind.
