Yes, and this is actually the only roundtrip which one is able to take on the line, as it is the sole train which turns and heads back to the city. The most challenging fan trip.
I've done it...sorta. I actually opted not to return via Metra, but to take an oddball Pace bus to Fox Lake and return on another Metra line. But I would not recommend such, as the bus stop is not easily identified nor the bus a typical Pace bus. So it might be missed.
Interesting you've done this, since I was considering doing the exact same thing myself! Taking that Metra run to McHenry some weekday morning at 7:30am(or whenever it arrives into McHenry), spend a day up there, then take a Pace #806 bus in the afternoon rush hour north to Fox Lake, and take a train on that line back to Chicago. I've wanted to visit Chain O'Lakes Brewery, and yep I'm really into trying all the different beer breweries out there. I've gotten to the point, where it's SUPER tough for me to think of any stations I haven't visited on the Metra system over my 10+ years of doing weekend pass trips to visit as many various stations as I could. Heck, I even did Manhattan, Harvard, and Elburn before, which says a lot! Not to forget the Mokena-Hickory Creek station once, which doesn't have much by it except mostly chain expressway motels and fast food by there. I can appreciate this station's purpose and good, which is to service people who live nearby, and that it is an easy way for travelers along I-80 to exit, park their car, and take the Rock Island Metra line.
BTW, I don't think it'll be that huge of a deal if the #806 bus doesn't have bus signs. I've taken different Pace buses myself in further out suburbs that didn't have marked bus signs, and was okay since the bus stops are marked with an icon on Google Maps. How different btw(vs. the typical look Pace bus models I've seen), is the look of the bus that runs on the #806? That's my bigger concern, more than the fact the bus stops don't have proper signage.
