Any Austin, Texas Amateur Astronomers here?

Hi,

My question is regarding Mansfield Dam as
I keep getting conflicting information.

Some say the dam was closed to foot traffic after 9/11 and never reopened.
Some say if you go on the right night (which night would that be?)
or have a telescope with you "they" will let you on the dam.

Can anyone here update me on this?

I am looking for a relatively dark location, not to far away from where I
live.
I have tried 2 fields here in Round Rock. One I was asked to leave by the
police
(what on earth can be harmful about a girl with a telescope?) and one was a
rewrite
of the "attack of the killer fire ants". Texans will understand how painful
that trip was.

Thanks,

jojo
