My wife's interest and participation has changed considerably over the years. At first we would take two small kids and a dog Adirondack canoe camping loaded into a 17' Grumman. it was good as long as a) it wasn't too far, b) bugs were few or at least manageable, c) it was warm enough to swim with a sandy beach (not always optimal in the Adirondacks), d) I did not insist on taking long bushwhack wilderness hikes from the campsite and dragging them along with me.
In later times, after for several years she was happy sending me off solo to '"do my own thing and recharge" once or twice a season, I then became a racer with friends from work. She is not herself a racer Kids were gone and that gave her a whole new role as my pit crew during my annual 3-day 90-miler race. She would transport me, my boat and team's gear day to day and set up our race end of day state campground campsites, but she always had the very welcome assistance of my team mates' pit crews to set up and cook meals. After my race partners moved on and I began racing on my own, campsite camping setup was too much for her to do alone. She got tired of the new crop of competing pit crews and attitudes they brought to the race. So for me to continue we began to stay at motels each night and eat at restaurants, which continues to this day. However, now with extra time during the day she volunteers to work as an official race timer , which she enjoys (I am pretty sure).
She willingly (I believe) assists me during canoe race training, dropping me off and picking me up at the end of the day with my local lake/river training, and especially for me and team mates when we paddle the 20-hour Cannonball-90 at least once each season.
While she still enjoys getting out on the water with me on occassion, her advancing hip arthritis gives her a lot of trouble getting into and out of a canoe these days, so her days in the boat are fewer now.
When I got invited to race the Yukon races, she was a natural, helping me plan and assisting others on my voyageur canoe team in all aspects of planning and travel here and there. She has been wonderful at that task for five trips to the Yukon and knows the routine exceptionally well. (after 5, she "thinks' she is done with that)
So with all of that I must give her at least a 30%, if not higher.
