You will be ok with attending a game alongside 25k fans who were tested 48 hours before, most of which went to work, school, supermarkets, restaurants, shopping etc. during that 48 hour period?
Fact is, nobody wants to pay $130 for a test they can get for free. Hence, nobody lining up at the tin can in miami to get tested. Ouch! Way too expensive to move, it closes during inclimate weather, very expensive to operate. Tents been around for thousands of years. Military and government loves them. Temporary and can be moved swiftly and inexpensive.
