Hi teecee,i think your be drawn to the grandstand as your 1st venture out on the island where you be able to walk round the pits to see the bikes as well as seeing all the TT riders,the road behind the pits is called Glencrutchery road where the start line is,one place
i do like to go is 350 yrs past the pits just before St ninians crossroads which is the start of the 180 mph Bray Hill section! Kirk Michael is also a must to see,you will get a good idea when you ride the circuit of a daytime where you like to go to watch the practice/racing,also if you up the north of the island pop into Jurby airfield where the riders go to check there bikes out,i think you will miss it this year but if you go again for the full practice wk they have classic racing on the Billown road circuit down in Castle town from 27th-30th May this year(think its called the Pre TT Classic,cheers Steve
