Three questions..ok maybe four..
Great questions Bob.
(1) Do I have to be a member to contribute to the trail work days? Can I become a member at the work day if I fill out the paperwork?
Anyone can join in an help out on a trail workday. No membership required. Just send an e-mail to trails (at) SWAMPClub.org and let them know to expect you. That way enough food, equipment and transportation to the trail work sites can be arranged.
I am not sure if you can even become a member at a work day. Our trail leaders are not equipped to handle membership forms, however, there is usually someone on a Sunday ride who is. Ask for Marty E and she will set you up with membership at a Sunday ride. (Unless you join through the main website at http://www.swampclub.org/join_renew.htm
(2) Do you ride after cleaning up the trail??
Sometimes we do, depends on how hard we work. Bikes are optional and when you bring your bike you can sometimes do trimming work so you basically ride your bike while working. That is fun: Get trail work credit for riding your bike.
(3) Do you need to bring anything when you come to a trail work day (besides a good attitude, some gloves)
Some water might help too. Drinks are usually provided for lunch but that doesn't help if you are out on the trails working up a sweat. This is especially important during the summer time.
Hops these answers help, thanks for asking.
