I like many others can't commute for work. After the last time gas went up rediculously high I cut out as much driving as possible and have tried to stick to that as best I can. With my work I can do some of my shopping after I'm finished working since I do do some work in grocery stores, drug stores, and dollar stores. So that does help. We just bought a home and are in the process of moving in. I don't think we'll get much out of a graden this year, but are planning on one for next year. I did get my blueberry bushes planted inthe ground instead of keeping them in pots, so hopefully by next summer we'll have some blueberries. We also bought two strawberry bushes (on sale at Lowe's for half price) which are also planted. Hopefully that will be a good start.
Also I'm considering after we get some debt (credit card) paid off, looking into getting solar pannels installed on our new home. No HOA to worry about, and there are about a dozen homes in the neighborhood with solar pannels.
