In practice, it's hard to enforce 6 feet when standing in line and anyone who is sick if spreading viral droplets in your vicinity that are carried by wind. I would be concerned having to stand in that line with potential Covid cases.
Assuming you need this, your alternatives would be a food bank, church, or grocery store (for what you could afford, etc).
Given they aren't checking ID's, or taking payment, and that schools tend to have a decent amount of open space, it's probably one of the safer options.
Now would be the perfect time to start testing food delivery using drones. Bonus points if the drones can be sprayed with disinfectant after each flight.
Drones are probably reasonable enough in a residential neighborhood of single family homes and duplexes, less practical for a large apartment building (unless they can fly right in the window).
In every group, there's going to be a small percentage of people who are selfish (look at the TP situation). So, how do you keep those people from running out grabbing the supplies each time you drop? You can't possibly drop all the supplies at one time from a drone.
