I don't know the reason, but I feel nearly intellectually crippled since losing access to the multitudes of blackboards available on college campuses. White boards do not even approach the utility of blackboards for me. People in this thread have suggested fine tipped markers and washable crayons—I will try them both!—but I truly feel I will simply not be able to recover the efficiency and value of a blackboard any time soon.
