Gravel driveway

["Peter Schauss" <schauss@worldnet.att.net>]

I need to extend my blacktop driveway in order to be able to park
my "regular" cars where they will not block the entrance to the garage.
The extended area will be about 20'x30'.

I am considering a number of options ranging from hiring someone to
do the black top to putting in some sort of gravel or blue stone.
If I choose the latter option, how deep should I dig the area out
and what types of fill material would be likely to work best?
