One of the reasons there could be less fans is what someone has mentioned already in that they have found something else to do on a Saturday since the COVID lockdown, which is the case with me and at least 2 other people I know, not something else to do, but I lost my job and my new job is now in Wales and I was a season ticket holder, I manage to get to get to a couple of home games a season when I come back to visit family, but have been to more away games i.e Chester, Wrexham, Curszon Ashton, etc so I think there are  a lot more reasons than just the owner keeping people away.  Even if I was living in Lynn now, it the team that matters most, like managers owner come and go but loyalties are to the 11 players that wear the shirt when they take to the pitch (coming back to Lynn for FA cup game, can't wait and hopefully see us win)
