From the comments of the previous post, directly from Bruce...
August 6, this Thursday.
We are really looking forward to having all of you over for some good eating and riding around the yard.
Some details to consider:
Kids 8 and under. A race around the yard. A great time to watch your kids riding their bike (bring their helmets).
Kids 9-13 Approx. 3 km course that will take them through the best off-road that you never thought we had. (bring their helmets).
Everyone else. You will do 3-4 laps of the 3 km course. I can't decide yet. We'll decide on the day. (Bring Your Helmet).
Bring lawn chairs.
BYOB. There will be a cooler of ice for you. All other refreshments and food are covered.
