City Park aka Emma Long is more ledgy with less embedded rock like Brushy Creek. The ledge heights range up to 6' (probably.  I haven't ridden there in a while) depending on the line you take.  Unfortunately, lesser skilled riders have blazed paths around ledgy areas, which then become ledgy, then those ledges got ridden around, ad infinitum, creating 20-foot wide "singletrack".   These ledges are a large part of why trials riders like the park. As far as riding after rain, yeah, it's the best trail in Austin after rain. 

So my friend recently invited me to go riding on his dirtbike at Emma Long. I used to ride dirtbikes in another state right up until kids and a knee injury pushed me into MTBs. Looking at the videos of Emma Long, it seems like it's on par with 1/4 notch? Or is it more like Double Down/ Deception? Trying to guage how out classed I'll be.  Also, I think I read that it's ok to ride after rains? Yea/ Nay?

yea...  was the last hold out with my posse of moto-heads...    that changed as we were at PACE and was to be the only one without an e-bike.     To my surprise...   there with a big red bow...  a new Levo with a card on it. A gift from my kid sister and nephew...   they had secretly worked with my bud and TJ's. have to admit...  it is a hoot...    not the same,  but fast and fun.   now if I ride alone..   I'll take the Hightower ...   but with a group of e-dudes it is a conga line through the trees.  

Next weekend, there is an event for running (AM)/ biking (PM) in Georgetown. I ran a 5K with the same organization late last year and it was really well organized. Looking forward to trying one of their bike events.  https://www.tejastrails.com/edge
