It sure is, Lloyd.
A young friend of mine is a certified welder, and works stints at nuclear power plants, and other jobs, from time to time. He just returned home a few days ago from Canada, where he had worked for about 9 weeks on a job. He had flown there, having nothing but his proof of vaccination, with no issues. When he got ready to leave and come back to GA he checked into the deal and found that he would have to be tested if he flew home, but not if he drove. If he had tested positive he would be isolated at some location and tested again in 10 days, near the border I presume. If he tested positive again, same deal. And on, and on. He said "No dice", and he and a couple other welders rented a vehicle to drive across the border, which they did with no issue, then drove to an airport and flew on home.
