Bicycle neglect

I left my bike in my garage, but the cold wet winter had its way and when i went to bike to work tuesday morning i aired up the tires and aired up the shock and tried to move it and discovered that the chain had rusted into a solid mass that would not change shape. I need a new chain, and it might be time for whole new gear packs (still on the original gears from 7 years and thousands of miles ago). It's time to explore that new bike shop that's 100ft from my front door. Too bad their hours are 12-7.
