The lowest hanging fruit to be plucked on limiting NR numbers from a financial cost and non opposition from MOGA would be the 1/2 price NR licenses in excess of the B-10 and B-11 cap that are sold OTC to former residents.

I do think that is the part that residents would be wise to target first, but I also think that changing season dates is probably a close second place.
