The conference venue is the Glenn Miller Ballroom in the University Memorial Center (UMC). The UMC is located on the West side of the CU Boulder campus.
If you plan on driving to the venue each day, we recommend using CU Boulder Lot 308. A parking pass for the week costs $16, and can be purchased from CU Boulder. Information on buying the passes is here: http://www.colorado.edu/pts/node/235.
