Was thinking the same. Driving to Hampshire from Norwich visiting family so could take the short trip to Swindon whilst there. However if it’s on Argyle Tv or Swindon’s I follow it would be another option to be less unsociable.
If it’s not it seems Argyle pick the only clubs to play who don’t allow games to be streamed. Torquay, Yeovil last season and again this year with Torquay. Most clubs have all games available. It’s only friendlies after all. Clubs don't tend to make much from these games anyway. Fairly sure Argyle said they make no profit from home games in pre season.
