Continuing my last message since I hit the 1000 character limit...
I also enjoy riding around the lake in McGregor Downs subdivision. It is a somewhat hilly ride and it is on the road but traffic is no problem in that area.
Hinshaw greenway is another nice trail that starts near Barnes and Noble on Maynard (it actually starts on Greenwood Circle about 1/10th of a mile away from Maynard) and it goes south across a pedestrian/bicycle bridge over rt. 64 and ends at "Kids together Park" by the Wellington Park Shopping Center. Sometimes I will ride the side walks to connect this trail to the Speight-Branch Greenway which starts at Tryon (between Piney Plains and Holly Springs) and goes south to Cary Parkway.
Perhaps we can get together sometime for a skills session to work on idling and backward riding and other skills. I usually get together with a coworker for Coker rides, skill sessions and muni rides.
The Lake Crabtree trail (black creek greenway) has some interesting hills. You can start at Old Reedy Creek Road and go to Dynasty, then turn right and go up the hill, down the hill and then turn left for the continuation of the trail. It ends at Maynard but if you cross the road you will see Godbold park and it has another trail that starts at the entrace of the park and goes about 1 mile to an elementary school on rt. 54.
On the other hand you can start from that same point and to into Umstead Park and ride the bike and bridle trail. Just ride along Old Reedy Creek Road into the park and when it passes the park boundary it becomes the bike and bridle trail. Even though it is not paved it is very smooth and won't give you any problems.
I also live in Cary and I'm kinda looking for a mentor of sorts. To give some background: a unicycle was my primary mode of transport while attending NCSU... but that was 10 years ago. Now I find myself trying to get back into it. I've logged about 50 miles over the past 5 weeks, trying to get my legs back in shape after all that time off.
My primary intended use of a unicycle is for touring. Just going down some of the nice, long greenways in our area - nothing off-road, not interested in doing tricks. I've got a 24" unicycle, so I'd likely just slow you down, but I'd also like to finally learn to idle and go backward.
Any recommendations on trails? The greenway near my house has a lot of hills, though they haven't been giving me too much trouble here lately. Shelly lake is nice, but not very convenient, it's a good clip from Cary. Lake Crabtree has a flat trail that I believe is close to 5 miles round trip if you start from Dynasty. Any others?
