I've been stung 4 years ago... through my waders... under my little toe... worst pain ever. ended up in hospital... (the venom caused seizures) then discovered a brain tumor in my precautionary scans to get my license back. it was slowly growing and would have been worse if it wasn't for that ray. tumor was low grade cancer, operation/radiotherapy etc etc... but that's another story.long story short, I've released countless rays off many beaches... and you DON'T need to harm them IMO.
