Mustang Show in Rockville, MD - Sunday

Unfortunately, I am still in college and finals are coming up so I am unable to get off campus for another 2 weeks or so. On the other hand, my father works a lot in the Maryland, Virginia, and DC area and may be able to attend. About how many cars/ mustangs do you plan on showing up at this show? I wouldn't want for him to drive all that way for a few cars (even though they are mustangs). Hopefully you will have some good weather for the show and maybe you can get a nice Mustang cruise together after the show is over.
