I intended to follow up with the vendor and see if they would tell me who purchased the swing, but never got around to it. We had a hunch who it was from, so I just operated under the assumption that we were right. JP finally followed up with that person last week and discovered that she DIDN'T send the gift.
So now we have this awesome swing for LJ and no one to thank for it!
Thank you anonymous horse swing gifter! We don't know if you meant to be anonymous and we're sorry for taking so long to publicly acknowledge your gift. Hopefully you'll read this and know we received it and that we love it!
