Hi N.~
Welcome to Illinois. I moved here from KS about 14 yrs ago (college)and never went back home....now my family is down in Dallas!
I belong to the Cary Moms Group and we have members from all over the McHenry area (a lot in LITH, Algonquin, Crystal Lake & Cary) the site is www.carymomsgroup.com and you can try it out for I think 30 days before you join...the fee is 10 for the year. There are playgroups broken down by age, large events, park dates, moms night out,kid free nights....you can do as much or as little as you want.
They also have other sub-groups...working moms, bf support,others I can't think of right now!
We change the park dates up and this month we have two in LITH one at Miller and Randall and the other is down Miller at I think Sunset Park....
Check the group out, it is a nice group of ladies and a large age range of children.
