I hope you can join us for the San Diego Hat Hike (Walk at Lake Miramar) on Saturday, June 11th, 2011, at 10 a.m.! It would be great to see you! All of the details are on SparkAmerica.. Please be sure to RSVP there, even if it's no. :)
Answer to your challenge question - Post whenever you like. I'm going to try and post any points I earn daily for the mini challenges. Otherwise, the sparkpoints and weekly points can be added at any point throughout the month.
