Learning to use my neighborhood properly

There are many places in this country where people sell fruits and veggies daily along the sidewalks.  Today, I needed (or really wanted) some bananas, strawberries, and sweet potatoes.  What did I do? Instead of going to the supermarket, I decided to just walk around my neighborhood.  I found one lady trying to get rid of some 'naners, since they were getting close to bad -- perfect for my protein shakes.  Then I walked up the street a little bit and found a man selling some really nice strawberries (for about 8 bucks), but they definitely look better than the ones at the super market.  I walked across the street and bought some sweet 'taters as well.  I should have bought the rest of my veggies there, but I went to the supermarket to get my sweet peppers instead.  This morning I was kind of a little mad at myself for not doing that any earlier in my time here.  I sometimes buy fruits on the street, but need to do more of it.
