I make no apologies for my post. Before I posted it, although I was in a hurry, I did a search on "nexrad" and immediately found the post that clearly referenced "gray nexrad".
(For some reason, the same search does not return the same results now.) But at the time Anne made her post I believe "gray nexrad" was easily findable. Or at least that was my belief when I posted my brief reply.
In the past I've always gone out of my way to post the link(s) that answer someone's question, even if they didn't indicate they've made any effort to find it themselves -- so cut me some slack. Next time, if I don't have the time I'll let others respond. Upon review, I suppose it was curt. A better brief reply would've been "Do a search for 'nexrad'".
