There are more than 1,200 registered lobbyists in the Capitol -- about 10 for every member of the Legislature -- but judging from the hiring that continues unabated there's room for courses like Lobbying 101. That's the introductory course taught by Ray LeBov, who worked for more than three decades in the Legislature and as chief lobbyist for the state court system. LeBov also teaches an advanced course, Lobbying 201. The courses he launched last June have been such a hit "most of the graduates of 201 are asking me to do a 301, which I'm considering."
