Thanks for the info re: GFCIs.
But the crux: Why is it bad to plug a power strip into another power strip? I do that in my garage when I need a few extra feet of cord.

If you are using it as an extension cord just for the length, that’s not a problem. If you have extra cords plugged into each one, with a total of 27 items essentially plugged into one outlet, you are probably trying to draw WAY more power than one outlet can give you.
A 15 Amp circuit can supply up to 1800 Watts (120V x 15 Amps) a 20 Amp circuit can supply up to 2400 Watts (120 Volts x 20 Amps). Remember, that includes all outlets on that breaker or fuse. Just add up all the Watts on everything on that circuit, everything should have the Watts printed on the bottom somewhere.
