Dry hopping

Im going to dry hop my latest IPA. Question is: Should i do it in the secondary or the keg?
Im using homwgrown cascades. If in the keg, should i put them in a straining bag or just let them float?

Pretty much up to you I guess. I DH in the keg and use a woman’s knee high stocking. Just tie it off & throw it in the keg for 7-10 days at room them & then into the kegerator, hops & all. Cheers!!!

+1 for in the keg with a stocking.

Thank you
