I have met hundeds of TC owners... many have been to our house for visits and we have visited many all over north america...
Plus, there have been more than 50 TC's in my driveway for help with modifications or repairs. Just out of friendship.
I've never been to a rally... the closest would be Hope Valley with 5 other TC's
I have allergy induced asthma... I avoid places where there is smoke (like camp grounds) and I don't expect others do camp without their fires.
Fewer people seem to be traveling... at least east of the Missisippi.
