We were stationed in Germany from 84 thru 90 and I was a mechanic working on snow removal equipment so I had to be at work no matter b what 7 days a week thru snow season. We lived 35 miles from the Air Base I was stationed at and made it to work everyday with out chains and only had to leave my car stuck twice. Once with the right front tire pushed into wheel well ( totaled BMW )
This last Apr we went to Portland Oregon and had to buy chains for the first time ever. Made it to the area to put the chains on before the mountain pass and as we were driving past people applying chains looking for a free spot we saw people near the front taking chains off so we just headed on without the chains. We were in the wife's 2010 Pruis and it made it with no problems, surprised me.
Your snow run looked like a blast wish we lived near others to get a group outing like you.
