I am new to the smoking habit, got a GOSM for fathers day and I think I've used it every weekend since. My poor grill is collecting dust though. Anyway the instructions recommend using wood chips and not chunks. I'm having trouble finding hickory chips in my area but the local Menards carries chunks. Do chunks work ok in the GOSM and if so do I need to do anything different using them vs chips. Any help will be greatly appreciated. I've been lurking on this site for several weeks and have learned a lot so far.
