i agree, it is very important to have a support system , i am new to this group but i love to talk to other moms in here ,it is a great start to a support system, or you could start your own . If you go to church, just ask around, talk to childrens services, parenting groups in your local area to find out if they have groups or if you could start one
I do belong to several FB and yahoo groups that are local to where I live and there are tons of field trips, and park days and activities for those that want face time. I do activities with them randomly. I just set up a field trip to a timber wolf educational center and we had over 100 homeschoolers attend on 3 different days.
We are so busy with sports (karate and gymnastics) and church and Boy Scouts that we don't have a ton of time for the Homeschool groups.
