I'm about 4.5 (a little less in match play, a little more for hitting). Would love to hit at, e.g., Signal Hill Park, or Metz Middle School or Jennie Dean Park. Email me at NeoKantian@aol.com.
What's your availability? I may be able to play on Sunday morning around 10-11am. I usually play at Stonewall Park, i don't have any problem playing in any courts around Manassas. Of the 3 you mentioned, Jennie Dean is the closest to me.
I think I can play around 11 a.m. or 11:15 a.m. tomorrow (Easter Sunday). Please email me at NeoKantian@aol.com to exchange cell phones and finalize arrangements.
