Had my first trip ever to Brimstone last week. Riding conditions were perfect. It has been dry but the trails were not too dusty. The waterfalls we went to were pretty much dried up with just a few trickles flowing. There was still plenty of mud to find if that is your thing but the overall the trails were not sloppy. It was an awesome several days to say the least. Made it out without any damage or issues which is always a plus.
