Dear Castro Street User,
This survey is part of the doctoral dissertation research I am conducting on the effect of street design on the use of "main streets". I would much appreciate your assistance by filling out the short questionnaire regarding your own use of and perspectives on Mountain View's Castro Street. The results will increase understanding of the use and effectiveness of Castro Street and other "main streets".
Please feel free to contact me at email@example.com with any questions. Thanks in advance!
