The ID NOW test is apparently not as accurate as PCR--more false negatives. But if it's good enough for Bonaire, it's good enough for me.
I'm having a difficult time finding the ID NOW test in my area. Walgreen's supposedly offers it, but every location in the greater Atlanta area that Walgreen's lists as providing it lists "no appointments available." This appears to relate to only the present day and the next day, and there doesn't appear to be a way to make appointments further out. I can't wait until 48 hours before my flight to chance some Walgreen's in the area will have an appointment or chance a walk-in.
A clinic in the area offers the ID NOW test for $160. Their instructions are very clear and allow you to make an appointment for whenever. I guess I'll dig into my wallet.
