You may find that you will put on more miles now that you are a "senior". The group we ride snowmobiles with were staying at the Villages in Florida a few weeks ago and they took a 70 mile golf cart ride! When we ride snowmobiles we seldom ride less than 100 miles, usually twice a week snow permitting! Our average speed is 35-45 MPH depending on trail conditions. Don't worry about your age, worry that your wife will start liking the sport so much that you ride more than you ever have at speeds she never liked traveling before.
I go to Colorado twice a year but mainly use my rigs around my little farm. Last trip to CO I was the only guy on atv. I hope the Wolverine is a good choice. I've looked at all the brands. Im an old hot rod guy so I will be adding mods for sure.
I called a local dealer and laid claim to a blue non EPS model today. They have it in, but are so swamped, it could take a week to have it in the rotation to get assembled. It's going to be a long week, but will be worth it with the deal they cut me compared to every other dealer I talked to saying that the MSRP was the price with no negotiating.
I go riding about 6 days a week, been retired for over 19 years now. I ride with a few of the fast young guys and it does keep you young. I just can't get the Stupid Racing Thing out of my system. I raced motorcycles for about 15 years then mt bikes for 5 years. I have over 10,000 miles on my 2011 RZR 900. It has a boat load of problems and cost a lot to keep it in good condition but the fun factor is high. I drive my Wolverine on long remote rides. Retirement is great. Everyday you get up and do anything you want. It doesn't much better then that.
