Peninsula Park - evening tennis

Looking for someone to play tennis with in the evenings, around 730ish at Peninsula Park in North Portland area.  

Prefer to play more for exercise and hitting practice, but if you want to keep score, thats fine too. I'm certainly not a beginner, but but the ol' backhand isnt a thing of beauty. 

I live just up from the park so would like to get in some exercise and fresh air after the kid goes to bed.

Thanks,

Ross
