According to the facebook page Rosfest says "goodbye for now."
I know there are members on here who have been to Rosfest(I've even met some of you guys there) so I thought I would post this for those who don't use facebook. Although I personally doubt RF will return I'm glad to see they are open to the possibility of it maybe returning at some point.
Kind of sad but that's the way these things go. RF obviously isn't the only casualty this year.
