Going to a WW2 weekend in reading PA - what Lens would you leave at home??

[TerribleTwins]

Going to the WW2 weekend in Reading PA this Saturday - believe it has static & flying displays & a battle re-enactment.

I'm taking my 80-400 & was wondering whether I could get away with taking only one other lens - either the 35-70 or the 17-35 (trying to save on weight!)

Any one been to this before? Is the wide angle going to give me any thing over the 35-70?

Thanks
