Here's a view of my reality. I teach the mechanical engineering capstone class at Montana State. We're in "hybrid" mode. Big classes are taught online. Labs, small groups, office hours are done "in person", or as i like to call it, "mask-to-mask."
i lecture once per week. This is online. Last semester, i had 6 design groups i advised. We would meet in a classroom designed for 35 students which now have a maximum capacity of 8. I would meet with each group once per week. We'd keep our distance, and would be masked the entire time.
I also have an "open door" policy - if i am in my office, my door is open, and i offer advice/programming help, etc. My office is pretty big, so i leave the window open (and with the door open, decent airflow), and allow students to work at a desk which is about 8 feet from my desk so i can offer advice/help when needed. I will probably have 6 groups again this semester.
I had one 'Rona test this fall. Negative 'cause i had my "wellness check" and they offered the test. I am pretty healthy ("run" 40 miles per week, cycle back/forth to campus (7 miles each way) every day) which means very little apparently, except that I am outside, so i am not vitamin D deficient. I will also be 60 years old in 3 months, so that puts me at a higher risk. it is what it is.
My point to all of this is that if you are disciplined, follow CDC guidelines, and avoid those who don't, you'll probably (yes, probably) be OK. There is a risk, but i do what i can to mitigate it. Outside of the university, i pretty much stay home ALL the time except if i have to go to the HW store (emergency). Otherwise, i order online. I am dong a full restore of my 2002 GG this winter, and i can source all of the parts w/o seeing anyone.
I have empathy for the students who are studying difficult subjects AND dealing with the 'Rona. It's a b!tch, and i see WAY more mental health issues now than i did a year ago. I am doing what I can to help them out, and am able to protect myself as well. So far, so good.
Everyone has to make their own decision. My priority is to not infect anyone. I don't see older folks, and so my risk of exposing high-risk people is very low. My wife is ok with how this is going - she knows the students need help now more than ever.
For what it's worth, we ride dirt bikes in National forests. we can ride all day and maybe see three/four people. I live about 90 miles from Yellowstone, and have NO desire to go there.
