Mark,when ya get in the US,your best bet is to take I-80 west.i believe its a toll road up until u get to the state of Iowa.
i'm a truck driver by trade,and travel to LA weekly.depending on weather,i have a northern rte or southern rte to take.so when i take the northern rte,i go I-80 straight across the US right into CA.then I-5 straight south to LA.from there its up to you depending on ehich part of the city you are going to.i weekly go to Ontario,Montebello,City of Industry and Carson.
to me I -70 is out of the way.and to go further south to catch I-40 is way out of the way from where u are coming into the US.
This time of the year,you'll hit bad weather.Wisconsin,Nebraska and really suck.i was stranded for a day about a month ago in OGALLALA, NEBRASKA because of weather.that is on I-80.then entering CA you'll be going down Donner Pass and Truckee,CA.which is one of the area with the heaviest snowfall in the country.just west of Reno,NV.
I-70 would take you thru Denver,CO and that state is a skiers paradise.then you would hafta catch I-15 thru UTAH.i was just thru there a cpl weeks ago.it is beautiful.but lotsa mountains.
and i-40 is what i usually take,but for you that is extremely unnecessary travel time.by the time you hooked up with I-40 in OK City,you could be 3/4 done with your trip.plus going thru Arizona,i have pix of snowfall in Flagstaff a couple of weeks ago.the middle of the state is at about 7700 ft elevation.they get lotsa snow there.
if your using gps,i bet it will tell you to take I-80.
GPS' are great.however, you really need to know your trip as well.a GPS is gonna tell you the shortest way to get somewhere.so in reality.I-80 will take you from OHIO right to CA.but if theres a road that runs alongside it,the GPS will have u get off the interstate for a couple miles,then return to it.so thats kinda silly.and i know for a fact in UTAH,my GPS always tells me to hop off I-80 and take another road for a few miles then get back on I-80.I just cant remember the exact rd number ATM.
also,a GPS will change as you do.say,if your GPS has u running straight across Canada and entering the US in Michigan.i'm talking, Saulte St. Marie.(a trip i made a cpl yrs ago from SSM to Montreal.)ok,your gps may route u to there.but you know you wanna head south twd Detroit sooner than that.so,thats what u do.then the GPS will re-route you from there.
so GPS' are really cool.but plan your trip ahead of time.you can use google maps and/or mapquest.com to get a route.just hafta type in your departure address and your destination address and either of these websites will give you an exact rte of the trip.either using shortest distance or avoiding tolls.then you can print it out and compare to what the gps is saying.
my best advice is to stay on the interstates.some of them have sucky areas full of potholes.but if their bad,what do you think the side roads will be like?know what i'm saying.
any questions PM me.i'm on these roads all the time and will help anyway i can.ill even give ya my phone number if needed.
also try to plan your trip to be driving thru major cities at night.less traffic,less starting/stopping= more enjoyable driving experience.
i hope some of this helps,i was really trying to explain in great detail so u could understand my directions.not because i think your 5 yrs old.lol!
