Kelly, Payment for informal presentations are not customary. That's not to say a nice token of appreciation along with a generous and sincere letter of thanks cannot be given. Our Career Services, Admissions, and High School recruitment departments has a lot of college-labeled items (notebooks, coffee mugs, do-dads, this-and-that's) that make for great token than-you. Nowadays, a $10.00 gift card seems to be a particularly popular token. So, token, yes, payment, no. By the way, I agree that good field trips and guest speakers are significant and memorable experiences for our students. Barry Westling
