Got a bunch a pickle buckets in the wood shed, ya can walk by it an smell pickles! But, the pickle smell don't bother me none, use em fer brinin an a couple brines later they just smell like brine.Just make sure you clean those buckets out really really well. My brother used to bring some home from Applebees and it took a long time of soaking and simple green to remove the pickle smell from them. Don't know what else could work better but simple green makes everything clean.
I'd make sure to support the Ziplock bag in case there is a leak. Here is my 2.5 gallon bag in action, inside a large "canning" potZiplock makes a 2 1/2 gal bags that works great on whole chickens and Colemans 5 day coolers are the bomb for any brining they come in all different sizes and can be found cheep at Walmart.
