chumming herring

[bart]

this may sound like a stupid question, and i've already had it answered once by a knowlegable fisherman, but i just wanted some other opinions. i've never chummed herring before, this year i'm planning on doing so while throwing plugs. i have a mesh eel bag that i was going to load up with little chunks, tie to my wader belt, and then wade out there on the bar(most of you know where i'm talking about). is this a good idea? basically i wanna know if i should worry about sharks at all. i was told that they aren't many inshore species of shark and that the most i'd have to worry about would be gettting bumped by a big fish(this happened to me last season in the dead of night, freaked me out! but i've been thinking about it more because of the shark sightings last year. i was actually wading out there this past fall when they were seen, helicopters and boats everywhere. talked to a surfer that said he saw about six of em. for my own peace of mind what do y'all think. thanks in advance.
