I posted this in the PA forum but thought I'd share with the rest of the IS community as well.
I'm probably not the first guy to think of this, but I found a way to get bait when my local bait shops are closed or out of stock. After finding my two bait shops closed the other night, I was passing by a Petsmart pet store and thought I'd stop in to see if they had something that would pass for bait.
To my surprise (and delight), they had a good stock of Rosie red minnows, wax worms, mealworms plus other assorted insect larvae and creepy crawlies. It saved my night and my trip. The minnows were on the small side (1-2") but they worked fine for jigging trout, perch and crappies. Just remember, many states ban goldfish as bait so be sure you are buying minnows and not goldfish.
I believe Petsmart is a national chain and has locations in a number of states. Further, I think most of them are open until 8:00pm or later. I'm guessing that many other pet stores may have similar stuff as well. You may want to keep this in mind if you are having trouble finding bait.
I hope this is helpful.
