I'm finding the 70 200 a bit to big for day to day use sometimes...I was at my childs sportsday today and I had my 70- 200 on and overheard someone saying my camera was over the top...
But with your lens hood on did they get outta the way when you were shooting?
I've found people love when I share picts of their kids with them (our kids on same team, I don't shoot images of kids I don't know), usually for soccer/etc I'll send a few to them via the weekly emails of the pratice/etc.
