The way I look at it, you're fortunate enough to go to the game and go back to your warm car. That little intermittent cold is nothing.
How long of a walk? Here is one of my own personal issues (to show how neurotic I am) . . . I hate bundling up to get to the RG but then not really having a place to put my coat when I get to my seat. I have to wrap it around my seat or sit partially on it. I finally moved up to row A where I can now put my jacket on the bench in front . . . but then where do I put my feet. I used to park in the garage to avoid all that, but then I got to leave early or literally spend over 30 minutes trying to get out of the garage. These days I usually drink downtown and take the max over at about 6:15. Works out great.
10 minute walk.. at least for me. I do understand the lack of space. But still, it's not such a huge deal in the grand scheme of things.
