No kidding about lights not working... pull up notams for pretty much
any airport, and you get one or several "Tower 4.5 SW 419 AGL lights
OTS" (or along those lines).

Some folk wisdom about towers, once told to me- if you picture the
tower falling over as you fly past it, and you are far enough away

Note use of "probably." Best bet is watch out and be careful.

There is a big (1300') tower in our instrument practice area where I

the altimeter with the other. At night I keep a bit farther away to
be sure. The students tend to do a decent job holding altitude
(under the "hood") after I mention that tower
