Much obliged, all!
As for adding locations, I considered it. But, as noted in the original post, some of these pics are pretty old and I've forgotten where I took them myself - so, as adma suggested, enjoy the guessing game (though, if you're really stumped, just ask and I can probably get you at least an approximation).
Speaking of which, I've just been stockpiling these pics since my old photo hoster disappeared, so please forgive the impending flurry of posts...
