Good choice on the mUni. I've been ridding for a couple of years with my son. It took me about 2 weeks to get where I could go 1/2 mile down the road. Everything came pretty quick from there. 1 Month in, I decided to hit the local trails. It was a eye opening expirience to say the least. It is a nice change from the bike. I actually think it is about 3X harder. WHen your first learning to ride, I recommend only 30 minuetes at a time. It can get pretty frustrating. Here is a pic and viceo of my son and me on the local trails.
