I would use transit happily IF there were open slots between 10 a.m. and 2 p.m. in the transit parking garage.
I hope serious thought is given to people like me who wish to go to and from downtown Seattle on a single bus during off-peak hours! I would hope that this would increase ridership!
I suggest building at least double the capacity of the current park and ride. You may be surprised how many people want to use transit and find no place to park.
