The impact of gas prices on your library, part 2

catablog picked up my posting and added to it (and tells a funny story about her mother's library). I left a comment there that included the following:

Now I can afford to pay for gas, but what about those who can't? So perhaps libraries need to look at how to provide services more cost effectively to their patrons whom this will affect the most? And maybe it isn't online services, but going back to bookmobiles (or high-tech bookmobiles with Internet access) or something else.

Since this problem (gas $) isn't going away overnight, we should look at the options and adopt strategies that will truly benefit our users.
