I was in regular air space once down near Daytona, and the controller must have been beating off or something (my initial thoughts), cuz next thing I know, these crazy old guys in their T-6s and a Mooney come blasting out from under a small bit of clouds at about my 1:00, headed right for me, so I dove that rusty little 152 I was renting really hard, and I don't know what, but those old farts did not see me, none of them manuevered to avoid me.
As I was "dodgin" the old coots, the approach controller comes on, Cessna 1............he pauses, and I key up, yeah I saw em.
Apparently they had just taken off from some little private strip, climbed really fast right at me, and ATC didn't really have a chance do to anything about it.
Then there was this one time, in a WELL maintained 152, where I was flying northbound along the Chicago lake shore at about 1000agl and 80kias, and I am now a little further north, just east of Palwaukee and the app controller comes on, kind of paniced, Cessna 970, traffic your 2 to 3:00 climbing fast a little lower than you, 2 miles, westbound.
At this point, I was a fairly fresh little private pilot, and didn't know if I was suppose to call him in sight, even though I didn't get an ATC advisory yet (didnt wanna tie up the radio). So I called back, have the traffic in sight and climbing. the controller, 2nd best app controller I ever had, just said thanks. I had watched this guy coming since he was 4 or 5 miles out.
Ended up being some moron flying just off the water in a twin something headed to PWK.
I don't count on VFR Flight Following very much. Most of the reason why I use it is so I can go over little airports and class C's so I dont have to worry about getting permission, usually. Handoffs have been pretty smooth for me when VFR. Never had a flight following denied or dropped either, except once in Florida, where there was a shift change, and the new controller dropped all 3 of his VFRs. Bastage
