***REMEMBER NEVER LOOK AT THE SUN WITHOUT PROPER PROTECTION.***
Here is Phil Plait's Everything You Need to Know About Next Week's Transit article, including how to observe it safely.
Toward the bottom he has a link to NASA's list of times for US Cities and for the rest of the world. It is useful to note that the times listed have some terminology:
External ingress: when Venus first touches the sun
Internal ingress: when Venus' other side enters the sun
Altitudes: the angular height above your horizon that this happens at. Often it is hard to see anything at <10 altitude due to trees/buildings/etc even if you have a clear view of the horizon. Unless maybe you're in Kansas.
Internal egress: when Venus starts exiting the sun
External egress: when it completely exits the sun.
(there's also the "greatest transit", but I think that's of less specific interest)
Note that times listed are UT. Take care to note whether it will be Jun 5 or 6 that your location will be able to see. Here in the US it will be on the 5th (in general, the western hemisphere will see it on the 5th).
The most fun way to go do something with this is to go to a local astronomy club or university if they are having an event. Since this is so rare of an event a lot of people are going to be doing things for it. Your next opportunity will be in 105.5 years, so get it while it's hot.
For many places in the US, it will be an evening event so go! I think the Sun has some very nice sunspots, and at least here there will be a talk and NASA presence as well. Many places may still run talks etc, even if it is cloudy.*I do know, but it's a sekret
ARRR!
