I have seen three Gander Mountain stores - Ocala and Lake Mary, Florida and Bowling Green, Kentucky. They are all visible from the interstate highway. I have only been in the one in Ocala because I could not take the time to explore how to get to the other two.
When you approach an area that has a Bass Pro Shop there will be a billboard along the interstate advising you that you are getting near the store and letting you know which exit to take. Not so with Gander.
At the Ocala store, even if you get off at the right exit, there is no sign telling you which street to turn on to get to the store. It just happened that I had time one day to search for the store and finally figured it out.
I searched for the Lake Mary store on my Tom Tom, but Gander Mountain stores do not appear on it under points of interest.
I really enjoy the stores, but I wish the company would put up billboards (even though I normally hate billboards) to direct us interstate travelers to the stores.
