Yeah its how I have done matches alone since the Old Man passed away in 2002.
Living many miles from Sheffield, (I travel by train) or take in the away games when there is a large ticket allocation. Sit in the home end at away grounds as well; did that for Reading already this season. (Drew the line at Milwall though).
To be honest, attending the matches at Hillsborough I get talking to people less than the away games; everyone knows everyone else who sit around them in the North where I try to sit.(Or did try to before this season) They know the seats that are available to POTG as it were, so you don't get involved in banter going around as not a Season Ticket Holder. Not a problem, just the way it is.
