I would think the food plot forum in the Game Management section would be best place for this type of Deer Feeder topic. (game management)
I'm not against adding another forum but many DIY projects fit well into other areas on the site, i.e., tree stand projects seem to work great in the bow hunting section and ground blind discussions work well in the rifle hunting forum.
We've had many diy type discussions here at the DHC and each always seemed to fit into the forums we already have.
I dont see the need to add another forum but If the majority of members think it would be a good idea then you have my support as well.
Democracy is two wolves and a lamb voting on what to have for lunch.
Liberty is a well-armed lamb contesting the outcome of the vote.
