^it'll be cool to finally meet yah
but yeah,depending on your bot,pics do help show other modes.
the only exception i think would be if you did some kind of actionmaster type bot where there isn't another mode.
in the past i've used a 8x11 home printed piece of paper with alternate modes pictured on it,but i've seen others which were a foot and a half by 2 and a half feet big. i guess the key would be to keep it within reason,if your bot is scout classed,you probably shouldn't have pics that take up half a table
and like others previously have said....."no touchy feely",unless it's your bot/custom.
be warned though,from what i can tell from the net,here and tfw,this year's shaping up to be killer!!!!!!
