Microcenter is probably the most consistent place. Not a huge selection, but some of the maintstream ones, to get a feel for switches on Keychron and some of the other big brands. Depending on where exactly you are, it's likely +/- 30min of an hour drive, which is only sorta "far" in US terms.

Frys predated the "mainstream" mechanical keyboard boom. If they were still around I'm sure they'd have even more (they were always larger stores).
