I'm in wine country (Kelowna), some nice side roads and nice wine, but more importantly on Fathers Day-June 18th- there is a large free car show down town(300- 400 cars on the grass in City Park). We put in last year around 35+ Porsche's from 356's right up to GT3 RS and doing again this year.
Also, any of our national parks are free this summer for our nations 150th.
