No apologies really are needed. i just wanted to state that you can't go through life scared of doing something or how someone will feel about what you do because of something that may have happened to someone else.
I do respect your opinion and yes it is admirable that you think of your sisters feelings but really don't let that stop you from doing something you may want to try.
What would your brother in law say if he could?
I know my father would say enjoy aviation and get all you can out of it and enjoy every moment of life.

Using a atv in the hunting experience doesnt make one lazy or take any of the "simple life " out of it . it just adds a different excitement to it and gives pleasure when the season is over. my son and i have begun to enjoy the prep for hunting season almost more than the hunt due to the tools like atv's and tractors. we are planning now to build more nice stands in remote areas and foodplots before next year.
they sure help.
don't condemn something until you have really used it.
