So glad you haven't seen any ticks. It's mostly in wooded property or high weeds. Rocky Mountain Spotted Fever is a tick related disease. Even though diagnosed I didn't get any bad symptoms.
The Lyme was a different story. I was bitten by a tick and developed a huge red circle around the area. I started losing my balance. I was put on antibiotics but still couldn't keep my balance...going down stairs, taking a shower, walking across the store parking lot...impossible without the sensation of falling. I felt a bit better after 6 months but still have symptoms, especially if I get other illnesses such as a cold.
Keep on the lookout for those bad boys!
