I use Mesa a lot more on the way home than on the way to work. The choice about where to cross Mopac
on the way home is a bit easier than on the way to work - Steck is out because the stop sign stops
you right in the middle of a nice downhill; I don't like going uphill on Mesa to Far West; and you
can't easily get all the way to Balcones southbound; so I always take Spicewood Springs.
