If you ride in the Marriotsville area, make sure you liberally apply tick repellant to your horse and yourself. Lyme is endemic, we used to live backed up to the park on Marriottsville. Whole family had Lyme and Babesia, all the dogs had Lyme. If you find a tick on you, put it in a bottle of alcohol and save it just in case. Make sure you tuck your pants into your boots, trim fetlock feathers.
