The NW Art & Air may be the best little late summer festival around: Watch hot air balloons ascend in early dawn flights Friday, Saturday and Sunday and illuminate the night sky during the magical night glow event, Friday the 26th (weather permitting).  Friday and Saturday Timber-Linn Memorial Park will come alive with music, artists, a vintage car show, family activities and food from a variety of vendors. Musical artists will give evening performances. For the adults, there’s a wine and microbrew garden.
