Date men and women from United States / Colorado / Lyons, 54 year old

Date men and women from Colorado, United States. Alrighty, I'm 50 now....
Single, two kids, live in a bit of a smallish town and by golly, somebody's missin out, so I'll do what I can. :)
My favorite things to do right now are coach my boy's basketball team, take my boy and girl skiing and on various world adventures, and hang out around home with them. They're with me half the time. I've been glad to get them on some nice adventures, including exploring Costa Rica on a two week trip that was only scheduled for one (had some splainin to do after that one to people like coaches and moms) snorkelling on the Big Island in Hawaii (we're talkin stayin in the 'loveshack', not the Hilton), Canyonlands, regular summer trips to the high altitude wilderness in Wyoming, regular ski trips to Telluride; and, this year to Cozumel for more snorkelling.
What I DON'T like doing is thinking to myself, "jeesh, coulda planned ahead to avoid this way to quiet night without the kids". I've got a great little life on the river North of Boulder, great job and home; and, now that the kids have started to suggest that maybe SOMEDAY they'd have more fun on our adventures if they "brought a friend", then I figure its time to take some action. I haven't quite mentioned to them that Daddy might also enjoy "bringing a friend" on some of these excursions.
I'm a lawyer in a previous life, and now produce music festivals.
I like my spring vacations to be somewhere warm, winter skiing, fall on the river in Nebraska hunting with my cousins and uncles and summer fly fishing in the high altitude wilderness of Wyoming.
I see alot of live music, of all kinds, and would surely love a compatriot for those missions as well as a co-conspirator for some cozy nights at home for some wine and a movie.
I'm not eager to leave my cozy home in the winter and drive into Boulder... but could be tempted for a nice dinner and music.
I'm not in great shape, and have been fairly sedentary this year. But, I can still get down the mountain on skiis, up and down the basketball court, wade across the river, hike through the mountains.
But a hiking/rompings/skiing/eating playmate would probably help alot!
And, was once told that I don't kiss like an American.
So there's yer Reader's Digest version.
Now what?
