I don't think anyone is going to be coming up from Seattle anytime soon. Its extremely hard to make an appointment for a covid test. You have to sit on the computer and just wait and wait till a appointment slot pops up and grab it. There is no alerts to your email nothing. Prior to the omnicron I could make an appt the day before a test.
I think the current test backlog is going to last till April or May at the earliest. Until than its once again South of the Border for entertainment, there are zero restrictions going to Mexico.
