Dr. C suggested that I purchase some Cactus Juice to repell ticks. Amazon.com has it for the best price. I hate wearing Deet products because of my MCS. Bug repellants always have some kind of perfume added to the product. This looks all natural so I'm going to get a bottle for me and another one for my daughter. She is a sea kayak instructor on Lake Superior which is a highly endemic area. She's one of the people that thinks Lyme can be cured with 30 days of ABX. GROAN! I think I was bitten for the 2nd or 3rd time last time I visited her in 2005.
