Hey there, I cant help you out with stores in your area, but I am from WI as well (North Eastern part) and is always nice to see more fellow WI members on here. I am always willing to trade plants and what not so you never know, maybe we will be doing business someday.
Cool man. I'm actually new to this and am just finishing getting everything ready for my first planted tank. Hoping to get it going this week or next and looking for some plants on the main forum.
