I've got house rep and congress info/addresses. help with committees?

went to the addresses you located.
googled what district the towns I belong to are, then found the house of reps on the list (congress is easier, of course.)

with the committe contacts, I didn't see an address I could contact

I saw each committee's group of people and most of them had to do with food, nutrition, ag, et al. but where do I send the durn envelope?
