I've got to respectfully disagree with the above post.
Leaving all the fan leaves/stalk ect is a lot of added weight and an annoyance to deal with later on.
I find it easier to trim all the fan leaves off in the field, if at all possible, and clip the stem into manageable pieces for hanging.
Never underestimate the smell of freshly harvested weed... It wreaks. It's best to double bag it in thick plastic and then put the bags into a storage container with a tight fitting lid. Last thing you want is to skimp on odor control if you end up getting pulled over.
Good luck
