Oh, wow, thanks! That's super considerate of you. I'm good with evaluating my abilities in/for the moment and am honest with myself (and others) when I think I'm not up for something.

The Indy museums were super helpful for learning how to estimate a new limit for me (walking). For instance, I learned it's much easier for me to do a slow but steady walk for long time than it is to walk somewhere, stand for a while, walk again, stand, etc.

In other words, I am a country-roads girl, not a stop-and-go-city-traffic girl. =D
