newblue87,
I have done freight with Fedex Freight, 7 wasted years, I went right back to food, I don't ever want to go back to freight, food is really steady, Sygma will probably be more steady than Sysco due to the fact that they do chain accounts, they never slow down. Its said that broadline slows in the summer, but I have only been with one food company where that was true, and that was only because they put all their eggs in one basket with the schools.
I say go for it, your young, you can make a great career out of food, its interesting and rewarding work, you get much closer with your customers than in freight, also you can always transfer to Sysco from Sygma if you get sick of doing the customized stuff. :)
Good luck to you, keep us posted on what you find out and what you decide to do!
