For Saturday, there is a Denny's that is close to downtown:
3600 Fox Street, Denver, CO

It is right off of I-25 at the 38th St exit. Do we want to meet in the parking lot about 9:00 AM? From there, we can drive together to get to 20th and Larimer.

On Sunday, 10 AM at GoG Visitor Center. I will already be down in Colorado Springs on Saturday night and will see you on Sunday morning.
