Be prepared to do some brush trimming and general trail repairs. Bring loppers or pruning shears if you own some, but tools will be provided if you can't bring your own.
Dress for the weather and be aware that this is tick season, so a deer insect repellent could keep the critters away. Sturdy work gloves are a necessity, waterproof shoes or boots are recommended. Bring something to drink and maybe a snack. Keeping hydrated in this season is very important!
