Thanks for going through each and every letter, cpg! Much appreciated :) Believe me, tho, making those changes required more brainpower than making the original, mistake-prone quiz! If there was a list for this kind of thing, that'd be lovely. Who knows, may start a series - Biggest Cities Containing _ Oh well, already made this so no point in remaking, but taking less time. Overall, I think I took... 2 or so hours on this? Not as hard as the first's process, I guess that's an upside.
It might yield another quiz though - Cities We Thought Weren't In The Top 5 Containing Letter But Really Are. Don't count on a high average score though
Thanks, Jerry! I explained above on the time. :)
