I always carry my IC-A3 with me....since I am taking pictures never know when I need the transciever side.
There are a number of folks I know at the field, and if I catch them before they leave ground frequency, they will normally give me a good slow taxi by so I can get a good picture of the plane.....or I catch a couple of friends on unicom in their warbirds who like to do a low level pass, I can get them to not just do a mid field turn out, but have them run the length of the runway to get the right angle.
