For the MACIE meeting on Friday, January 18, if you do not wish to try to find parking up at the capitol complex, there is a shuttle from the west side of the Capitol Hill Town Center which makes a contiuous loop every 5-10 minutes.  Here is a map https://leg.mt.gov/content/sessions/66th/CapitolCourtesyShuttle_Brochure_FINAL.pdf.

The meeting is in Cogswell Building on Lockey/Broadway.  There is an entrance on Lockey Ave.  You would use the elevators to get up to the second floor, Rooms C205/207.
