When looking for a dark site, there are a few things I look for:
* Any astro clubs nearby?
* If not, choice of site firstly needs to be safe as you may be by yourself, or to protect the expensive gear of fellow astro-heads.
* Out of town is needed to reduce influence of light pollution
* Prospective site needs to have wide expanse of sky- Ovals, sporting fields, even out-of-town airfields. Seek owner's/manager's permission. I've developed a relationship with the manager of an Airfield two hours west of Sydney, all he asks for in return is a case of his preferred brew. The more folks that come, the more the cost is shared out.
* Not too close to the coast to minimise the detrimental effects of the sea air, if it can be helped.
* Suss out facilities/locals. Mozzies are never welcome, but niether is spraying Aeroguard near astro-gear. (funny enough, at the Airfield we attend, the local tiny bats see to the mozzies for us!!). Possums, roos, wombats, etc, can frighten several years out of your life.
* Though a good view of the sky is wanted, the site would be ideal if there was some shelter from wind.
Just some things to keep in mind for a dark site,
