Has anyone used these? We went out to Alamo for 3 days and never got one crawdad in our trap. We never saw a crawdad. I only say 2 crawdad shells on shore the whole trip. Do these traps work or is Alamo short on crawdads? We used bacon, hotdogs, potatos, all left overs. We did catch a baby bass. It was about 2 inches.
