Jim: The plants are out but the spring bloom won't really hit for another month. Yes, it was the Imperial sand dunes I was riding through. In another month, it will be absolutely carpeted in flowers and will be even more beautiful.
On the WD. I know what they do and how they work and they are a great addition. I at no time felt like I needed them though. Perhaps with a lighter truck or a heavier trailer or in higher winds, then I might need to get them out (The bars are kept inside the trailer). Many folks don't know that you are supposed to unhook the spring bars when you are going over sharp transitions (Such as drive ways to gas stations) as it puts alot of stress on the hitch. I have seen hitches cracked because of not doing this. I'd rather not have to hook up and unhook several times a trip due to this.
Again. I can't speak for anyone else but with my tow vehicle and trailer, the WD system isn't absolutely necessary for me to have an easy tow.
