Technically speaking....
Checkboard has it right...if your at a VFR airport, your on your own for terrain clearance...and when you do that trying to get ahold of ATC, in the clouds, you will be asked to 'maintain your own terrain separation through X altitude' That said, if you got in, you can get out...VFR, and it you can't get out VFR, in uncontrolled airspace...it's nice to have taken a good look at the property when you came in, so you know which way your leaving that night in IMC. Needless to say, some VFR terrain type charts, climbing right over the airport or right to a navaid, or airway, like a bat of hell to the nearest, closest, lowest piece of protected airspace is how I do it.
