It has been a while since I have had a chance to catch up with this thread. Lots of interesting posts, thanks all.
For those of you that like to read the technical journals, the CDC puts out a newsletter with links to research articles.
Here is the link.
Now for the reason for my absence ... we took a 4000 mile 224 hour tour of the central and southeastern states. (That works out to just under 18 MPH for the entire trip ... driving or not.) During the trip, we noticed various levels of masking and social distancing the WORST was in Tennessee and Arkansas. The best was Texas. I was shocked that Texas showed the most adherence to masking and social distancing.
We only stopped at Cracker Barrel to eat and then it was only a few times. In all but one (in Tennessee) they used every other table and nothing on the tables. One did have the salt and pepper shakers on the table. All of the servers and 90% of the employees had masks on. Masking by patrons was another story ... about 50% in all but Tennessee ... where it was about 10% masked patrons.
Rest areas along our route [I30, I20, I49, I10, I95, I26, I40, I75, I69, I80, I65, US33, I71, I75, I64, I65, I40, I30] were decent, for the most-part. Most had the really cheap toilet paper and blow dryers. However, the rest areas along I-40 were small with limited large vehicle parking, if they were open at all. Several rest areas were closed for construction, others were just closed. The Tennessee and Arkansas rest areas were the ones that were mostly closed.
Diesel prices along our route varied a lot. We used "gas buddy" several times to find decent prices. The prices we paid ranged from $1.839/g in Texas to $2.359/g in IL.
We picked up BAD FUEL at the Triumph 27 BP station at 9855 Dry Fork Rd, Harrison, OH 45838 ... beware!
We, too, have noticed that major cities and counties around the nation have started requiring the use of masks by employees and customers alike. This is something we can get behind. I do believe that it will become more "normal" to wear a mask in public over the next few months ... but then I am an optimist.
