Do Thermal Imaging Sunglasses/Goggles like the ones used in that GI-Joe movie, actually exist in the Military?
1. Four-season or all-weather tires are best for Portland. Your touring tires will probably be okay, though. Snow tires have studs in them that are there to grip better on ice, but they get WORSE traction on wet pavement, and they also grind up the roads. Since it only snows about twice a year in Portland, that's not a good trade off. (Use chains for the twice a year it does snow, and any ski trips you make to Mt. Hood.) 2. Yes, there are a lot of on- and off- ramps for the urban freeways (I-5, I-205, I-84, OR-26, and OR-217). Many of them are metered they only let one car at a time merge in. Just wait your turn and go when you get a green light (but not when the car ahead of you gets their green light.) Use your eyes as you accelerate, and try to match the speed that you're merging into. Then you can speed up or slow down as needed to fit in a gap. Most Oregon drivers will let you in easily if you're at least polite enough to use a turn signal (If not, then they must be from California.) Off-ramps are generally posted with an exit speed limit if you just go that speed you'll be fine. 3. Oregon has some of the cheapest auto registration fees in the country. If you really like your Cherokee plates, then I suggest that you call the DMV to get clarification on that. 4. I think that it's 90 days. (I know that OR DMV requires that you inform them of address changes in that timeframe.) 5. Oregon DEQ does emissions tests for cars registered in urban areas. You'll need to pass before you can get tags (and every two years to renew). There's a bunch of stations, you drive to whichever one you want, they do the tests (different for different years of cars), and if you pass, you pay the fee. DEQ will handle DMV registration renewals for you at their station (so you'd pay both fees.)
No. The Most Annoying Sound Ever is the Sound of a Police Siren, Accompanied by flashing Blue Lights, and the Realization that a Speeding Ticket is Coming. Top That !
