Yes, until Seattle gets the Sonics back, it's worth it!
A surprising number of people drive from the Seattle area and even Vancouver BC for Blazers games.
Season is over
I wouldn't drive across the street for a basketball game...but, there are lots of places to stay, eat, and park close to the arena, and trimet has service nearby to the outer areas. I myself have driven down to watch games (hockey) or concerts and stayed overnight. Check through the team's website for package deals.
We drove from Seattle. Spent the night. We made a night out of it. Its a long drive for just a basketball game.
