Sometimes the suggestion is subtle. This was my conversation with SA Approach last week:
"San Antonio Approach, (MyCall), 3 thousand, direct Stinson Airport"
"(MyCall), San Antonio, cleared for the visual approach Runway 14 Stinson"
"San Antonio, (MyCall) cleared visual 14"
........
"(MyCall), San Antonio, be advised there is a level 2 rain shower north east of Stinson, do you still want the visual?"
"San Antonio, (MyCall), affirmative - I see the cell and will have no problem maintaining full visual conditions for the entire approach to 14"
"Roger (MyCall), contact Stinson Tower 118.2".
........
There was a hint in there somewhere, but conditions didn't warrant a request for a contact approach. As it was, I would have been able to maintain basic VMC to the ground if I were not under IFR.
I did consider requesting a contact approach on my way up to Tyler last month, but the holes in the clouds were just not big enough to allow me to drop in. So I took the GPS approach instead, and I was quite glad that I did.
