The view from section 101 is excellent. I normally hate the corners at stadiums and arenas but the seats are angled extremely well towards the field.
If you get rows 1 thru 6 in this section, you will have one of the best views of the player tunnel in the entire stadium. Unlike most NFL stadiums, both the Lions and the visiting team enter and exit the same tunnel. All of the lower level sections at Ford Field have 40+ rows so you will have quiet the walk to and from your seats to get to the main concourse. The steps aren't nearly as steep as they are on the upper level though.
I loved how the franchise incorporated the warehouse into the stadium. If you get a chance, give Poletown Sausage a try even though their sausages are terribly expensive.
