Do I need to wear scent control clothing and use scent free sprays, shampoos, etc?
If you own scent-loc type clothing it will help in some of the blinds you may be hunting. Most of the blinds are small brick buildings which contain scent really well. I would not go out and purchase scent-loc type clothing just for your African hunt. As far as scent free sprays/deodorant/shampoos, yes I would recommend you use them. You will have to bring them with you because they are not readily available here in Africa. I know they are a real pain to pack with your gear because of the weight and chance of leaking. I would suggest that if you are coming over with others on the hunt bring just enough for all of you and place these items in a zip-loc type bag or even vacuum seal pack them if you have one of those units. This will prevent leaking all over your other hunting gear.
