Learning wheel trueing

[PamNY]

I'm reviving this thread to confirm that it's maybe not a good idea for me to true my wheels at home by myself without a truing stand?

I did true a wheel once in my bike repair class, but it's been a while, and I had a truing stand and an instructor more or less guiding what I did.

I do have the option of going to the DIY bike workshop, using their truing stand and consulting the mechanic about any problems.

ETA: if I go to the DIY bike workshop and all I'm going to do is wheel truing, is there any reason to take my entire bike? With the weather so cold, I'd rather take the wheels off and travel by subway.
