He is a good dude. We held some training down at Telluric (in Brunswick) and had lunch with him and did some drills with him while there too. He is knowledgeable, but with a very down to earth teaching attitude that students on any level can appreciate.
I train fairly often and driving to training is pretty normal for me. With that said, if the class was longer than 1 day, and the drive was about 1.5 hours or more, I would probably stay the night.
Makes it easier to relax and recover for the next day.
