There's one just over a mile away from my apartment. Sometimes when I need to buy food or supplies, I jog there, and then I get exercising and running errands out of the way at the same time
There's another one, only about half a mile away, but their stock is pretty sad looking, so I almost never go in.
I've got a Petsmart, Pet Supplies Plus, Walmart, and Meijer within 15 minutes of me. The LFSs, on the other hand, are at least 30 miles away (and only one that i've been too, and another i need to go to).
I get a lot of my fish at my club meetings, which are once a month, and i have to drive about 25 miles to get to it.
There are 3 chains and 2 privates within 5 minutes. I'd say there's about 10 within 30 minutes, one being my favorite LFS. There are 3 within 45 minutes I haven't visited yet that are supposed to be very nice. While it seems like a lot of choices, I'm not very fond of most of them because they're either chains with the same old or privates I'd rather not shop at for various reasons. Recently I've gotten most of my stock either from my favorite LFS or my local club.
Excellent family owned LFS less then a mile away, one of each of the big 'P's within 10 minutes each. Although I do outside sales so make a point to stop by just about any LFS or hobby shop in the area on a given day
I've got at least 8 LFS within 20 minutes from me (probably more I haven't found yet). That doesn't include the numerous Petsmart, Petland, and Petco's.
