YES they work. They are a great producer for their price.

I especially like their 4'' grubs.

There craw worm work great as a jig trailer or Texas rigged  

Yum is Riverside lures.  Yum is what Riverside called it's scent.  When PRADCO bought Riverside, they changed the name to Yum and discontinued a lot of the old Riverside lures.

Riverside's are awesome at 97 cents a bag. What I have found is that most all of the Riverside baits I see are just YUM baits that were thrown in a Riverside bag and sold in the bargain bin.

i am a huge fan of the riverside air worms...i guess thier not made anymore but a few years ago i stocked up on them & have plenty to last a wile...i fished them like a senko & always catch fish on them

I really liked the riverside crawbugs and now the yum crawbugs

I use there grubs (white) for trailers on my spinnerbaits always use a trailer BTW
