For me, it depends on what the TFR is for. If someone high profile like POTUS is in town, and you're fairly close to the nucleus, I would be careful. The threat isn't with the FAA and the legality, but with local PD who are ignorant of NOTAMs, TFRs and FARs, but just know that the prez is in town and are extra cautious.
In this case I would go ahead and fly, but if someone with a badge asked me to stop, it would be best to do so. Waiving a printed copy of the NOTAM probably wouldn't get very far.
