So... only some rules need to be enforced ? My region even has a spot to check for it on the annual tech sheet and as per the head of tech I do need it (I don't just complain, I do actually ask & communicate with my region & SCCA). Larry is correct, must be with the log book and available at all times.
Again, no issue in producing it when issued your first log book, just that you need to ever again and it cost $200 for a copy of a paper SCCA already has.
