Narrative:

I was flying my PA32-300 (cherokee 6) from cny to my home base, trk via salina, ut, thence to mlf and MVA. About halfway between mlf and MVA I encountered increasing turbulence and rapidly deteriorating visibility. I decided to change course to the nearest airport, tph. I radioed for conditions and was told tph was IFR (I am presently VFR only). My situation was that all quadrants were now IFR. I decided to put down where I was and made an off field landing 79 SM east of tph on us 6. I lnded safely and remained overnight in tph. I returned next day, took off and continued on to trk. Incidently, there is a closed field just west of where I put down that I am now told and saw is just 10 NM from my position that has a brand new 7000 ft runway belong to the air force. Had it shown on the chart as a real airport, I would not have been in the danger that I was. See las vegas sectional N38:20:00 W116:16. I was advised that VFR was not recommended for west nv and the sierra due to obscuration, turbulence, etc. However, my (very) limited experience with flight service is that they almost always say 'VFR not recommended.' I tried to push it. I got lucky, god smiled, kissed me and made it good.
