Ditto for me. Remember that a significant portion of us, even the regulars, are not from California and are able to get to Yosemite far less often than we'd like (I'm certainly speaking for me but I'm pretty sure several others feel the same). For us, we have to live vicariously for most of the year so photos, whether brilliantly artistic ones are simple snapshots of what some obscure trail looked like when you hit the really overgrown spots, trip reports and even GPS tracks are a godsend for those of us can't get enough of the park (and even though he seems to spend more time there than many of the rangers, I think it's safe to say that even chick-on loves seeing trip reports and pictures!
)
So by all means, keep 'em coming!
