kal, you took the words right outta my mouth! ;~)
seriously, i couldn't tolerate either city because i can't stand hot humid weather. lots in both places. if i were forced to choose, i'd go for atlanta because its geography is a *lot* more interesting, imo - not completely flat, w/only tropical vegetation. also, it's a tad less humid & wet on a year-round basis. and, there's actually some semblence of seasons, w/some leaves changing colors in the fall & coming off the trees in the winter, etc.
ymmv, doug s.
