I was asked to pass this on by Steve at High Gear bike shop. A group of peeps are starting the Thursday evening rides back up again, starting April 8th at 5 PM (this week). Here's the recurring monthly schedule:

1st Thursday of every month - Lynx Lake area - meet at start of 305 at Ranch trail .
2nd Thursday - Thumb Butte - meet at thumb Butte parking Lot.
3rd Thursday - 396 - meet at Schoolhouse Gulch.
4th Thursday - Granite Basin - meet at Cayuse.
5th Thursday (when there is one) - Thumb Butte again.

On days when a larger group shows up, there might be an A and B ride option.

After the ride we all meet at Plaza Liquor next to Goodwin street Pharmacy. They have killer pizza and beverages.
