Only like to do RFing (video precisely, though I prefer to watch the train with my eyes) with not more than 3 persons (I hate overcrowding)...I am too much concerned about uniqueness,i.e,I want to capture all unique and rare to see trains which other RFs can't capture.The most favourable time of RFing for me in my local area is after sunset & before sunrise,I hate daytime...Love to explore unknown sections.Mainly inclined towards gathering Historical documents about trains.And I always do RFing with my best friend (who is also an RF) as we are always lucky when we are together...:)
