still a big question mark. I spoke with a warden in the field and he indicated there "may" be a grace period but he could NOT confirm that fact.
MOST LIKELY your first encounter with an enforcement agent in the field will include a warning. That's just a guess though, NOT advice to ignore the law. I'm fairly certain the top brass will give the word on when to go full ahead with enforcement, however, I'm also pretty sure if they are with belligerence and provoked in any way they can enforce this law immediately.
You may not like the idea, but how about calling the warden in the area you are staying right off and talking to him man to man and see what he says about that specific time frame when you arrive at your destination.
I need to say it again, these guys in the field are about 100x more understanding than some of the guys they recently replaced. They know this thing got dropped on us pretty quickly and that a lot of folks already bought licenses, tickets, and reservations.
