It is a good test, even when there are a number of ways to get there without a car. I do it every know and then, and our car hardly ever leaves the garage during the week. It's also good to do just in case you have to walk that far or further.

If you test it and it works, it may be a better option that sitting tight in an office or other location. Once you know you can do it and can assess how hard it is, then you can compare it to your others options when need arises.
