I'm getting old and am a whitewater kayaker. You have to go where the water is which means a lot of long road trips and long weekends. Setting up and tearing down camp constantly wears you down. Now I pull in. Sleep. Can drive part way and sleep at a truck stop. Much nicer. Mine has the bed over the garage so bikes and snowboards can just live there all the time too. Most creek and freestyle boats fit inside too until I get around to putting the racks on. Then I'll also have an awning and solar.
I keep it simple and just use a shared caldav list. Works on any client that can speak it. It's not specific to grocery, but I've found that amount of intricacy less efficient anyway.
I keep my paid off subie around, but I do like driving the camp converted van around because I can just sit and relax without having to go all the way home.
I'd love to get money out of politics. Make political advertising illegal. Give candidates a web site to post their resume. That's it. No more tv, radio, magazine, web, or newspaper campaign ads.
This solution admittedly requires a bit of experience and knowledge of how it all works. It blows the doors off most bundled or commercial things you'll find though.
"politician" should not be a career.
