This monday I will be driving back home to Portland OR from San Diego CA for thanksgiving break. I am planning on doing the 1k mile journey in one go via Interstate 5 the problem is that the weather report is forecasting 4 to 7 inches of snow in the pass and only vehicles equipped with snow tires or chains will be let through. I have had some experience driving in snow and ice but a trip of this magnitude, most of it which will be at night, is going to be something new. Does anyone hear have any tips for driving in snow and with chains and any ideas where I can purchase chains that will fit the rovers 20'' rims. Thank you and wish me luck on my journey.
