This is an interesting one. After a really abysmal start to the season Gainsborough have picked up dramatically in recent weeks and have actually won their last three home games (against Barrow AFC, Harrogate Town & Bradford Park Avenue). So not too surprisingly
My Computer has this down as a narrow home win. I'm not totally convinced though so I'm going for a repeat of last season's result at the Northolme:
Gainsborough Trinity 2-2 Boston United (525)
