Natural supports! All you need now is a 'potato canon' and a tennis
ball with some fishing line tied to it. (Think long needle through the
ball). Use the fishing line to pull up the rope that will pull up the wire.

I don't know that you're going to have much luck, being that close to I-30.
I went to Google earth, and checked... My -approximate- calculations say
that if you're on the corner lot, you've got about 120' to the street,
running the antenna east and west (which is cool, since you're north of
me, and it'll be broad-side north and south).
If you're the 2nd, or 3rd house from the corner, your lot is still only
about 120' deep. That's how deep -my- lot is, here.
What I finally wound up doing, was to string up a full-wave delta loop
(installed on a vertical plane) apex'ed around 60'. The top comes down,
like a pyramid and the bottom wire is pulled away from the support
structure. I feed that with 450-ohm ladder line, and an open-wire
capable, 2kW, Heathkit SA-2060 impedance matching device.
the antenna -was- an inverted vee. I just closed in the bottom of the
Vee, and made a loop.
73, and everything
