my rule for me... my rule for my kids... you do what you want to do for you or your kids

No Helmet... No Bikes
it is a simple rule
a rule from the start
a rule for things now

No Helmet... No Bikes

Nerf Guns got a similar rule
No Goggles... No Gun

I guess when they get older..
No Glove... No Love
but they may be a little young for that

no catchy phrase for this one... but already started telling them
Driver has been Drinking? Don't get in the car

Kid Bicycle Accidents on the Rise... many without helments
