We should call it Tax Payer field. Sc**w Safeco. The Safe is an out standing beautiful park. Great views. These days of miserable Mariners performance most games show only 20,000 fans. Buy the cheapest seats available then go to the upper deck and sit in better seats than the ones you bought. Move from the nosebleeds in the upper deck to the lowest seats in the upper (row 10 and up). Behind home plate. Up the baselines. Excellent views
Walk down Occidental Ave. Buy the usual ballpark food at 60% (?) of what it costs inside the park. You can take in any food, but nothing liquid, not even water. However you can bring in an empty bottled and fill it with Seattle water. Seattle water is much safer than commercially bottled. Seattle water is inspected by the City. There is zero independent quality control of bottled water. Also the bottled stuff ends up in the landfill.
The retractable roof is a thing of awesome engineering. Feels like you are entering the Death Star. Dress warm until late June. The roof will shield you from the rain, but not the wind blowing off Elliot Bay. The view of the Bay, City, Mountains from the picnic are on level three is outstanding. Sunset, wow!
Comfortable seats. Even the proletarians' seats have back.
