Hi Windsong,
I too had difficulty with walking alongside traffic. The reason you became disoriented/unbalanced I believe, due to over stimulation.  Cars moving fast, noise, visual field is large and expansive so there is much to take in through our senses.  I find wind in my hearing ear difficult too.  Tends to make me "swoon".  Ear plug is essential tool and truly helps.  I have many hidden in different places, car, bathroom (for hairdryer), by my keys, in my purse for use every time.  I no longer chance going without.  If I can block one of my senses it seems to help me last longer on walks outside, in mall, grocery story, etc.  I also found my shoulder are no longer stuck to my earlobes.  
Boppie,
I have handicap tag that I use if I am out in the evening.  I am not fully confident walking from my car to the entrance, but it helps knowing I don't have far to go.  I am considering buying a cane just for the evening walking.  Never considered a cane before, don't know why?
Lora,
LOL.  I have similar reactions to my husband crunching up plastic chip or pretzel bags during a movie.  It's as if the bag is against my ear!  And I loved the "old saying...."  I'm going to start using that one!  And your description of a pinwheel made me laugh out loud as I had the pinwheel arms this morning while teaching my yoga class.  We were in a balancing posture on one leg and before you know it, my arms were extended out and wheeling about!  Love it when that happens, makes me humble.  I smile inwardly knowing what a sight I am to my students.  I think it helps them to know even us teachers are off balance from time to time.  
Brenda,
Can I have one of your T-shirts?  I'm size small.  Love that one too!
Thanks everyone for your posts.  They put a smile on my face and in my heart!
