Narrative:
I was traveling to fat from dvo to pick up a family member. Norcal approach, ZOA, stockton approach all indicated that they were too busy to provide TA's, which I believe was due to the fact that a tfr over fresno was causing a great deal of work for controllers. At level stable cruise at 7500 ft, I caught a glimpse of movement out of my left periphery. It turned out to be some sort of business turboprop, probably a beechcraft B200, on a collision course. I took evasive action (climb and bank) and avoided a collision. I can't imagine that the other pilot didn't see me, but I did not see any evasive action being taken by the other aircraft. My magnetic heading was 110 degrees. I believe that the heading of the other aircraft was about 250 degrees. Our closing velocity was quite high, probably more than 200 KTS. The majority of the fault for the incident lies on my shoulders and the shoulders of the other pilot. See, be seen, and avoid will be taken to heart by me and, I hope, the other crew. The value of having ATC provide separation was underscored. In the future, I will probably avoid high altitude cruise unless I can get radar advisory services for my VFR flts.
Original NASA ASRS Text
Title: C172 PLT AND A BE20 HAD AN NMAC IN NCT CLASS E. VARIOUS CTLRS REFUSED TO PROVIDE TA'S BECAUSE OF A TFR IN THE AREA.
Narrative: I WAS TRAVELING TO FAT FROM DVO TO PICK UP A FAMILY MEMBER. NORCAL APCH, ZOA, STOCKTON APCH ALL INDICATED THAT THEY WERE TOO BUSY TO PROVIDE TA'S, WHICH I BELIEVE WAS DUE TO THE FACT THAT A TFR OVER FRESNO WAS CAUSING A GREAT DEAL OF WORK FOR CTLRS. AT LEVEL STABLE CRUISE AT 7500 FT, I CAUGHT A GLIMPSE OF MOVEMENT OUT OF MY L PERIPHERY. IT TURNED OUT TO BE SOME SORT OF BUSINESS TURBOPROP, PROBABLY A BEECHCRAFT B200, ON A COLLISION COURSE. I TOOK EVASIVE ACTION (CLB AND BANK) AND AVOIDED A COLLISION. I CAN'T IMAGINE THAT THE OTHER PLT DIDN'T SEE ME, BUT I DID NOT SEE ANY EVASIVE ACTION BEING TAKEN BY THE OTHER ACFT. MY MAGNETIC HEADING WAS 110 DEGS. I BELIEVE THAT THE HEADING OF THE OTHER ACFT WAS ABOUT 250 DEGS. OUR CLOSING VELOCITY WAS QUITE HIGH, PROBABLY MORE THAN 200 KTS. THE MAJORITY OF THE FAULT FOR THE INCIDENT LIES ON MY SHOULDERS AND THE SHOULDERS OF THE OTHER PLT. SEE, BE SEEN, AND AVOID WILL BE TAKEN TO HEART BY ME AND, I HOPE, THE OTHER CREW. THE VALUE OF HAVING ATC PROVIDE SEPARATION WAS UNDERSCORED. IN THE FUTURE, I WILL PROBABLY AVOID HIGH ALT CRUISE UNLESS I CAN GET RADAR ADVISORY SVCS FOR MY VFR FLTS.
