Hello Randos!
I have just added the Lowell Observatory 200k brevet (https://ridewithgps.com/routes/28357056) to the schedule on May 27th. This route will start in Thorpe Park at the base of the original Lowell (where Pluto was discovered.) We will also visit 2 additional Lowell Observatories, in addition to the NPOI (https://lowell.edu/research/telescopes-and-facilities/npoi/).
