I am lucky enough to have traveled to every single city & stadium in Major League Soccer except LAFC & Atlanta.
Fortunately for me, I will check those two off my MLS map in August & September.
And when I do, I will release the most definitive & comprehensive ranking of MLS cities known to the internet.
The ranking will be based heavily on important things like stadium atmosphere, fan experience, proximity to civilization &/or the city you're claiming you represent, to the not so important things like media meals, CSC friendliness & ridiculous stadium photo restrictions.
