Overlaying vectors on raster

Hi All,
Im working with Tiger data in the standard old geographic non-projection,
and am attempting to overlay streets on top of aerials pulled in via WGS
from USGS. The problem I am having is that the streets are WAY off in
every location I try. I realize the Tiger data is not terribly accurate,
but I have seen others do a much better job of overlaying the data. The
aerials I am requesting are in EPSG 4326 (which is I believe WGS84
geographic) while the Tiger data is in EPSG 4269 (which is I believe NAD83
geographic.) I wouldnt think the datum would make that much of a
difference.
The link below is to an example map that shows how far off the streets are:

Any ideas or suggestions?
Thanks,
Randy
