Eventually, you probably want to get on to I-90 (the Mass Pike). This goes right into downtown Boston, so find a busy onramp downtown. If you're in the suburbs already, a tempting spot to start might be by the Riverside MBTA station, but you'll probably find very little traffic going your way. If you can get a short ride just as far as one of the [[service plaza]]s, you'll likely have much better luck.
Route 9 is an excellent road to hitchike hitchhike on: lots of traffic, plenty of stoplights and [[gas stations]], and a decent average speed. You can probably get to [[Worcester]] faster along Route 9 than by taking the Mass Pike.
